Motion and Time

In this topic, we will learn the different kinds of motions exerted by a rigid body. It also discusses different theorems, rules and examples for a better understanding.

This topic covers the concept of speed. The movement of vehicles are dependent on speed by comparing the distance travelled by them in a unit time. The speed is the total distance covered divided by the total time taken.

In this topic, we will study how to measure any time interval. It also explains the use of cesium in the atomic clock to measure the time. SI unit of time and the department responsible for the maintenance and improvement of physical standards in India are also discussed.

In this topic, some activities are given which explains on how to measure the speed of a moving object. The speed is the total distance covered divided by the total time taken.

This topic states that the distance-time graph represents the motion of objects in pictorial form. This graph for the motion of an object with a constant speed shows a straight line.
