If not, given an example.
A car traveling at 60 km/h, stops on applying brakes in 10 seconds. What is its acceleration?
A car starts from rest and it is travelling with a velocity of 20 m/s in 10 s. What is its acceleration?
Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.
Reason: Acceleration can be produced only by change in magnitude of the velocity. It does not depend the direction.
