01 Physical World Quick Revision
1. Science It is exploring, experimenting and predicting from what we see around us. It is a systematic attempt to understand natural phenomena.
2. Physics It refers to the study of the physical world, i.e. the study of the basic laws of nature and their manifestation in different natural phenomena.
3. Scope and Excitement of Physics To define the scope and excitement of Physics, it is categorised into two groups, on the basis of magnitude of physical quantities involved in it, i.e. macroscopic and microscopic groups of Physics.
4. Macroscopic Group of Physics It deals with the subjects included in Classical Physics. It consists of phenomena at the laboratory, terrestrial and astronomical scales.
Classical physics can be classified as
● Mechanics It deals with the study of motion of particles, rigid and deformable bodies and general system of particles. It is based on the law of gravitation and Newton’s laws of motion.
● Electrodynamics It deals with the study of electric and magnetic phenomena associated with charged and magnetic bodies. It is based on the laws given by Coulomb, Oersted, Ampere and Faraday.
● Optics It deals with the study of phenomena related to light, working of human eye, telescope, microscope, etc.
● Thermodynamics It deals with the study of the system in macroscopic equilibrium considering changes in internal energy, temperature, entropy, etc.
5. Microscopic Group of Physics It deals with the study of constituents and structure of matter at minute scale of length, i.e. at the scale of atoms and nuclei or even smaller than these. This group of Physics can be studied under the subject Quantum Physics.
6. Fundamental Forces in Nature There are following four fundamental forces in nature
● Gravitational Force The force of mutual attraction between any two objects because of their masses is called gravitational force. This force was discovered by Isaac Newton.
● Electromagnetic Force The force associated with charged particles is called electromagnetic force.
● Strong Nuclear Force It is the force which binds the protons and neutrons together inside a tiny nucleus.
● Weak Nuclear Force The force which appears only between elementary particles involved in nuclear processes of radioactivity like b- decay of a nucleus, etc.

1. Physical Quantities All the quantities which can be measured directly or indirectly and
in terms of which laws of Physics are described are called physical quantities.
These can be divided into two types, namely fundamental and derived quantities.
● Fundamental Quantities The physical quantities which are independent of other physical quantities and are not defined in terms of other physical quantities are called fundamental or base quantities.
e.g. Mass, length, time, temperature, luminous intensity, electric current, amount of substance, etc.
● Derived Quantities Those quantities which can be derived from the fundamental physical quantities are called derived quantities.
e.g. Velocity, acceleration, linear momentum, etc.
2. Physical Unit The standard amount of a physical quantity chosen to measure the physical quantity of same kind is called a physical unit. The physical units can be classified into following two types
● Fundamental Units The units of fundamental quantities are known as fundamental units.
● Derived Units The units of measurement of all other physical quantities, which can be obtained from fundamental units are called derived units.
3. System of Units It is the complete set of units, both fundamental and derived physical units.
The common system of units used in mechanics are as follows
● The FPS System It is the British engineering system of units. It uses foot as the unit of length, pound as the unit of mass and second as the unit of time.
● The CGS System It is the French system of units, which uses centimetre, gram and second as the units of length, mass and time, respectively.
● The MKS System It uses metre, kilogram and second as the fundamental units of length, mass and time, respectively.

03 Motion in a Straight Line Quick Revision
1. Rest If the position of an object does not change w.r.t. its surrounding with the passage of time, it is said to be at rest. e.g. Book lying on the table, a person sitting on a chair, etc.
2. Motion If the position of an object is continuously changing w.r.t. its surrounding w.r.t time, then it is said to be in the state of motion. e.g. The crawling insects, water flowing down a dam, etc.
3. Types of Motion
On the basis of the nature of path followed, motion is classified as
● Rectilinear Motion The motion in which a particle moves along a straight line is called rectilinear motion. e.g. Motion of a sliding body on an inclined plane.
● Circular Motion The motion in which a particle moves in a circular path is called circular motion. e.g. A string whirled in a circular loop.
● Oscillatory Motion The motion in which a particle moves to and fro about a given point is known as oscillatory motion. e.g. Simple pendulum.
On the basis of the number of coordinates required to define the motion of an object, motion is classified as
● One-dimensional Motion (1-D) The motion of an object is considered as 1-D, if only one coordinate is needed to specify the position of the object.
● Two-dimensional Motion (2-D) The motion of an object is considered as 2-D, if two coordinates are needed to specify the position of the object. In 2-D motion, the object moves in a plane. e.g. A satellite revolving around the earth.
● Three-dimensional Motion (3-D) The motion of an object is considered as 3-D, if all the three coordinates are needed to specify the position of the object.
This type of motion takes place in three-dimensional space.
e.g. Butterfly flying in garden, the motion of water molecules and motion of kite in the sky.
4. Point Object An object is considered as point object, if the size of the object is much smaller than the distance travelled by it in a reasonable duration of time. e.g. Earth can be considered as a point object in its orbit.
5. Position It is defined as the point where an object is situated.
6. Path Length or Distance The length of the path covered by the object in a given time-interval is known as its path length or distance travelled. It is a scalar quantity, i.e. it has only magnitude but no direction.

04 Motion in a Plane Quick Revision
1. Scalar Quantity is the physical quantity which has only magnitude but no direction. It is specified completely by a single number, alongwith the proper unit.
e.g. Temperature, mass, length, time, work, etc.
2. Vector Quantity is the physical quantity which has both magnitude and direction and obeys the triangle/ parallelogram laws of vector addition and subtraction.
e.g. Displacement, acceleration, velocity, momentum, force, etc.
3. Representation of Vector A vector is represented by a bold face type or by
5. Modulus of a Vector The magnitude of a vector is called modulus of vector. For a vector A, it is represented by | A | or A.
6. Unit Vector It is a vector having unit magnitude. A unit vector of A is written as A$ . It is expressed as
an arrow placed over a letter, ®®®
In cartesian coordinates, i, j and k are the unit vectors along X -axis, Y -axis and Z -axis.
It has no unit or dimensions.
7. Equal Vectors Two vectors are said to be equal, if they have equal magnitude and same direction.
8. Resultant Vector It is the combination of two or more vectors and it produces the same effect as two or more vectors collectively produce.
Two cases for resultant vectors are as follows
i.e. F, a, b or F , a, b.
The length of the line gives the magnitude and
the arrowhead gives the direction.
4. Types of Vectors Vectors are classified into
two types polar and axial vectors.
● Polar Vectors Vectors which have a starting point or a point of application are called polar vectors. e.g. Force, displacement, etc.
● Axial Vectors Vectors which represent the rotational effect and act along the axis of rotation are called axial vectors.
e.g. Angular velocity, angular momentum, torque, etc.
05 Laws of Motion Quick Revision
1. Momentum Momentum of a body is the quantity of motion possessed by the body. It is defined as the product of its mass m and velocity v and is denoted by p.
Momentum, p = m v
2. Conservation of Momentum According to this principle, “In the absence of an external force, the total momentum of a system remains constant or conserved and does not change with time”.
If S Fext = 0, then momentum p = constant. 3. Equilibrium of a Particle The forces acting at the same point or on a particle are called concurrent forces. These forces are said to be in equilibrium,
5. Tension When a body of mass m is fastened with the string, then the weight of the body acts downwards while a force acting just opposite to the downward force for balancing it is called tension.
= 0. theorem, when three concurrent forces F1, when their resultant is zero, i.e.
i i=1
4. Lami’s Theorem According to this F2 and F3 acting on a body are in equilibrium, then
F1 = F2 = F3 sina sinb sing F1 γ F2 βα F3

Static Friction Force of friction which comes into play between two bodies, before one body actually starts moving over the other is called static friction and it is denoted by fs .
Limiting Friction Maximum value of static friction which comes into play when a body just starts moving over the surface of another body is called limiting friction.
Thus, fs £ fs (max)
The value of limiting static friction f s (max) between two given surfaces is directly.
06 Work, Energy and Power Quick Revision
1. Work Work is said to be done by a force, when the body is displaced actually through some distance in the direction of the applied force. Thus, work is done on a body only if the following two conditions are satisfied
● A force acts on the body.
● The point of application of the force moves
in the direction of the force.
2. Work Done by a Constant Force Work done by the force (constant force) is the product of component of force in the direction of the displacement and the magnitude of the displacement. Then, the work done on the body by the force is given by
Work done,W = F × s
SI unit of work is joule( J ).
1 2 -2 Its dimensions are [M L T
Case II
i.e. maximum work done by the force.
When F and s are perpendicular to
each other, i.e. then
W =F×s=Fscos90°=Fs(0)=0,
i.e. no work done by the force, when a body moves in a direction perpendicular to the force acting.

where, F x , F y and F z are the rectangular components of force in x, y and z-directions, respectively.
5. Conservative Force If the work done by the force in displacing an object depends only on the initial and final positions of the object and not on the nature of the path followed between the initial and final positions, such a force is known as conservative force. e.g. Gravitational force is a conservative force.

1. Rigid Body A body is said to be a rigid body, when it has a perfectly definite shape and size. e.g. A wheel can be considered as rigid body by ignoring a little change in its shape.
2. Rotational Motion (Fixed Axis of Rotation) In pure rotational motion, every particle of the rigid body moves in circles of different radii about a fixed line, which is known as axis of rotation.
e.g. A potter’s wheel, a merry-go-round, etc.
3. Centre of Mass A point at which the entire mass of the body or system of bodies is supposed to be concentrated is known as the centre of mass.
