Question

1.What is Acceleration ? Explain its formula and SI unit in brief.

2.An aeroplane attains a velocity of 200m/s in 30 seconds on its track. Calculate its acceleration?

3.Explain uniform and non uniform acceleration by Velocity-time graph.

4.A car accelerates uniformly from 5m/s to 10 m/s in 5 s. Calculate its acceleration?​

Answer 1

Answer:

The rate of change in velocity is called acceleration.

acceleration=velocity /time

the SI unit of acceleration is metreper second

1) acceleration=200/30=6.6m/s

Answer 2

Answer:

Ans 1 Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. when an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
