The magintude of displacemnt is equal to the distance coverd in a given interval of time if the particle .

Explain clearly, with examples, the distinction between : (a) magnitude of displacement (sometimes called distance) over an interval of time, and the total length of path covered by a particle over the same interval, (b) magnitude of average velocity over an interval of time, and the average speed over the same interval. [Average speed of a particle over an interval of time is defined as the total path length divided by the time interval]. Show in both (a) and (b) that the second quantity is either greater than or equal to the first. When is the equality sign true ? [For simplicity, consider one-dimensional motion only].

The graph of the total number of alpha -particles scattered at different angles in a given interval of time for alpha - particles scattering in the geiger- marsden experiment is given by

Assertion: The average speed of a body over a given interval of time is equal to the average velocity of the body in the same interval of time if a body moves in a straight line in one direction. Reason: Because in this case distance travelled by a body is equal to the displacement of the body.

The motion in which the object covers equal distance in equal intervals of time.

For a moving object the distance covered by it is always greater than or equal to the displacement of the object in a given time interval . Comment .

If a particle covers equal distance in equal time intervals, it is said to be in.
