02 Units and Measurements - Quick Revision
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.

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.

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.

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 ).
