Answer 1

Explanation:

uniform acceleration:

when an object is moving in a straight line and its change in velocity over a period of time or interval remains constant is called as uniform acceleration.

Example:

suppose a car moving in a straight line with its initial velocity 5m/s at t=5 s.

Now, at t=10s its velocity is 10 m/s.

At t=15s it's velocity is 15 m/s.

Here the velocity of car is increasing by 5m/s at each time interval of 5 second.

Hence , the car is in uniform acceleration.

few more example of uniform acceleration are as listed below:

A ball rolling down the slope.

When a bicycle rider is riding the bicycle on the slope where both the pedals are engaged.

A kid sliding down from the slider, etc...

Characteristics of Uniformly Accelerated Motion:

If the direction of both acceleration and the change in velocity is the same then it will result in positive acceleration.

At the same time if the direction of acceleration and the change in velocity is different or in the opposite direction then it will result in negative acceleration known as retardation or deceleration.

With positive acceleration, the speed of the object will either increase or decrease and with the negative acceleration, speed of the object will be slowed down, hence it is known as retardation.

• uniformly accelerated motion means the object or a body is possessing a constant acceleration. Constant acceleration doesn’t mean zero velocity. So the definition of uniform acceleration or uniform acceleration definition states that- if a body is under motion such that the amount of change in its velocity in equal intervals of time will be constant.
