What is meant by the term retardation? Name its S.I. unit.
Give one example of the following motion:
Uniform retardation
A body is moving vertically upwards. Its velocity changes at a constant rate from 50 m s-1 to 20 m s-1 in 3 s. What is its acceleration?
The velocity-time graph for a uniformly retarded body is a straight line inclined to the time axis with an obtuse angle. How is retardation calculated from the velocity-time graph?
Draw a graph for acceleration against time for a uniformly accelerated motion. How can it be used to find the change in speed in a certain interval of time?
Distinguish between uniformly and non-uniformly accelerated motions.
Out of energy and acceleration, which one is a vector?
A car is moving with a speed of 50 km/h. One second later, its speed is 55 km/h. What is its acceleration?
The graph shows how the velocity of a scooter varies with time in 50 s.
Work out: Deceleration
A car accelerates to a velocity of 30 m/s in 10 s and then decelerates for 20 s so that it stops. Draw a velocity-time graph to represent the motion and find:
The Deceleration.
