Match the following. 1. a. Circular motion 2. b. Oscillatory motion 3. c. Linear motion 4. d. Rotatory motion 5. e. Linear and rotatory motion

1-c When there is a change of position of an object with respect to time, then it is called motion. The motion in a straight line is called as linear motion. Sliding of a child on a slide is an example of linear motion. 2-d The movement of a body about its own axis is called rotational motion. For example, spinning of a top and the rotation of the earth on its own axis in 24 hours. 3-b Oscillatory motion is the motion which comes back to the same position after a fixed time interval. It is a periodic motion. For example, a pendulum or swing. 4- a The motion of an object in a circle is called a circulatory motion. For example, a swirling stone tied to the rope. 5-e The motion in a straight line is called as linear motion. A car moving on a straight road is in linear motion, whereas the tyres of the vehicles are in rotational motion. 1. c. Linear motion 2. d. Rotatory motion 3. b. Oscillatory motion 4. a. Circular motion 5. e. Linear and rotatory motion
