Give one example of the following motion:
Uniform retardation
Draw velocity – time graph for the following situation:
When a body is moving with variable velocity, but uniform retardation.
What happens to the stepwise increasing speed-time graph when the size of each step is made very small?
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.
