Motion and Time Class 7 Science Notes – Chapter 13

The basic unit to measure speed is meter per second. Time can be measured with periodic events such as a periodic motion of the pendulum. This is used in watches and clocks. We can represent motion in a pictorial form by the distance-time graph. When an object is moving with at a constant speed, the distance-time graph is a straight line.
