When will you say a body is at non-uniform acceleration?
Fill in the following blank with suitable word :
If a body moves with uniform velocity, its acceleration is ..............
Derive the formula : v = u + at, where the symbols have usual meanings.
Differentiate between uniform acceleration and variable acceleration.
A body, initially at rest, starts moving with a constant acceleration 2 m s-2. Calculate: (i) the velocity acquired and (ii) the distance travelled in 5 s.
How can you find the following?

Can you suggest a real-life example about the motion of a body from the following velocity – time graph?
A packet is dropped from a stationary helicopter, hovering at a height ‘h’ from ground level, reaches the ground in 12s. Calculate
- the value of h
- final velocity of packet on reaching the ground. (Take g = 9.8 ms−2)
A body is thrown vertically upward with velocity u, the greatest height h to which it will rise is,
