(d) Velocity
(e) Speed
Ans.​

Answer 1

Explanation:

(a) displacement

ans: shortest distance between two bodies

si unit : meters

(b) force

ans : si unit : newton

Answer 2

1) Displacement- the shortest distance between any 2 path

Unit-metre

2) Force=mass×acceleration

Unit-Newton

3) velocity-displacement/ time

Unit-m/s

4) speed-distance/time

Unit-m/s
