Question

Qs Change in velocity divided by time for it is called acceleration Find the acceleration in
going up and falling down?​

Answer 1

Answer:

Acceleration is a vector quantity which tells us how change in velocity with respect to time.

That is acceleration=change in velocity/change in time.

If a particle free falls under gravity then there is constant acceleration or if a car moves same velocity then there is no accelerartion

Answer 2

Answer:

if the body is going up then the acceleration will be negative that is -9.8 m/s² . and if body is falling down then the acceleration will be positive i.e. 9.8 m/s²
