A. what is meant by the term ‘acceleration’? State the SI unit of the acceleration.
B. Define the term ‘uniform acceleration’. Give one example of a uniformly accelerated motion.

Hint: To solve the question we have to know about acceleration and also about velocity. We know that, Speed is the rate at which the position changes. The normal speed is the removal or position change (a vector amount) per time proportion.

Complete answer:
Acceleration: Acceleration is the name we provide for any cycle where the speed changes. Since speed is a speed and a bearing, there are just two different ways for you to speed up: change your speed or shift your course—or change both.
SI unit of the acceleration \[m/{s^2}\].

Uniform acceleration: A body has a uniform acceleration in the event that it goes in an orderly fashion and its speed increments by equivalent sum in equivalent time frames. For Ex: Motion of openly falling body, bike going down the slant, ball moving down in slanted plane.

Note:
We have to know that, In the event that an item's (speed) is expanding at a steady rate we say it has a uniform speed increase. The pace of speed increase is consistent. On the off chance that a vehicle accelerates, hinders at that point and speeds up it doesn't have a uniform speed increase. On the off chance that the speed of the molecule changes at a steady rate, this rate is known as the consistent speed increase.
