A ball moves on a smooth floor in a straight line with uniform velocity 10 m s-1 for 6 s. At t = 6 s, the ball hits a wall and comes back along the same line to the starting point with the same speed. Draw the velocity-time graph and use it to find the total distance travelled by the ball and its displacement.
How can you find the following?
Velocity from a displacement – time graph.
Can distance covered by a body be less than the magnitude of its displacement?
Give the name of the physical quantity that corresponds to the rate of change of displacement.
