A body is moving along a circular path of radius R. What will be the distance travelled and displacement of the body when it completes half a revolution ?
A body when projected up with an initial velocity u goes to a maximum height h in time t and then comes back at the point of projection. The correct statement is ______________
From the displacement-time graph of a cyclist given below in the Figure, find The displacement from the initial position at the end of 10 s,
Figure (a) shows the velocity-time graph for the motion of a body. Use it to find the displacement of the body at t = 1 s, 2 s, 3 s and 4 s, then draw on Figure (b), the displacement-time graph for it.

Can you suggest the kind of motion of a body from the following distance – time graph?
Write the SI units for measurement of distance and displacement.
Calculate the distance and displacement in the following case:
The displacement is zero when the initial and final positions are ______.
Displacement can be zero but distance never.
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
