1.	ne acceleration and retardation and explain acceleratedmotion and retarted motion.4. Defi
Answer» Acceleration of a body is defined as the rate of change of its velocity. So, when the velocity of a body is not uniform (it is changing), the motion of body is said to be accelerated. Example:Suppose a car starts off from rest (initial velocity is zero) and its velocity increases at a steady rate so that after 5 sec its velocity is10 m/s ,then the car is said to have an acceleration of 10-0/5= 2m/s square and motion is said to be accelerated motion. Retardation : means DECELERATION When the velocity of the body is decreasing ,it is said to beretardation. When a body moves in a negative acceleration ,it is calledretardation. EXAMPLE: when we apply brake , the car decelerates , this is known as retardation

Answer»

Acceleration of a body is defined as the rate of change of its velocity. So, when the velocity of a body is not uniform (it is changing), the motion of body is said to be accelerated.

Example:Suppose a car starts off from rest (initial velocity is zero) and its velocity increases at a steady rate so that after 5 sec its velocity is10 m/s ,then the car is said to have an acceleration of 10-0/5= 2m/s square and motion is said to be accelerated motion.

Retardation :

means DECELERATION

When the velocity of the body is decreasing ,it is said to beretardation.

When a body moves in a negative acceleration ,it is calledretardation.

EXAMPLE:

when we apply brake , the car decelerates , this is known as retardation
