Motion and Time ( Points to remember)

Average speed is the total distance traveled by a body divide by the total time taken to cover that distance.

Measurement is the comparison of an unknown quantity with a known quantity

Motion is when a body changes its position with respect to time.

Non-uniform motion: A body is said to be in non-uniform motion when the distance traveled by the body at fixed intervals of time is not the same.

Speed is the distance covered by a body in unit time

speed = distance divide by time

Uniform motion is when a body moves in a straight line, covering an equal distance in an equal interval of time.


 The to and fro motion of a simple pendulum is an example of a periodic or an oscillatory motion. The pendulum is said to have completed one oscillation when its bob, starting from its mean position O, moves to A, to B and back to O. The pendulum also completes one oscillation when its bob moves from one extreme position A to the other extreme position B and comes back to A. The time taken by the pendulum to complete one oscillation is called its time.

Units of time and speed

The basic unit of time is a second. Its symbol is s. Larger units of time are minutes (min) and hours (h). Since the speed is distance/time, the basic unit of speed is m/s. Of course, it could also be expressed in other units such as m/min or km/h.

Once you know the speed of an object, you can find the distance moved by it in a given time. All you have to do is to multiply the speed by time. Thus, Distance covered = Speed × Time

There is also another meter that measures the distance moved by the vehicle. This meter is known as an odometer.
