PREVIOUS KNOWLEDGE

Students can give some examples of motion from their daily life.

MOTION Today we will learn different types of motion.

CONTENT PUPIL-TEACHER'S ACTIVITY STUDENT ACTIVITY

MOTION

When a body changes its position with time in comparison to other body at rest ,the body is said to be in motion.

A ball is rolled in forward direction.

Is there any change in the inital postion of the ball?

Did the ball take any time to change its position?

Teacher's Statement

Will define the motion as given in content.

Yes, the position has changed.

Yes


LINEAR MOTION

When a body moves in a straight line the its motion is known as linear motion.

A ball is rolled in forward direction.

Is the ball moving in straight line?

what do we call such type of motion?

Teacher's Statement

Will define the linear motion .

Yes, its moving in a straight line.

(No Response)


IRREGULAR MOTION

When a object moves in different direction then it is said to be in irregular motion.

Have you ever seen a flying bee?

Is its movement in a straight line?

Teacher's Statement

Will define the irregular motion .

Yes

No,it moves here and there without any regularity in its directions.


OSCILLATORY MOTION

When a object moves to and fro from its initial position , then the motion is known as oscillatory motion.

Example

Swing & pendulum

The teacher will tie a stone with a thread and move the stone to and fro from its initial position and will ask the questions:Have you ever seen a swing ?

How it moves?

Is there any difference between the motion of swing and the motion of the pendulum?

What we call such type of motion?

Teacher's Statement Will explain the oscillatory motion .

Yes

To and fro from its position

No, They are same.

(No Response)


CIRCULAR MOTION

When a object moves in a circle its motion is known as circular motion .Example:Motion of a moon around the earth.Motion of wheelMotion of hands of clock.Motion of electric fans etc

Does the earth revolve around the sun?

How the electric fan moves?

Have you observed the motion of the hands of the clock?

How it moves?

What is the scientific name of this motion?

Teacher's Statement Will explain that such type of motion is called a circular motion.

Yes

In circle

Yes

In circle

(No Response)

RECAPITULATIONToday we have done types of motion.Some examples are given below, name the type

of motion.

Rotation of the earth around its axis. Motion of top Hands of a clock Rolling of the ball on the floor Motion of train Motion of player of hockey Motion of swing. Motion of needle of the swing machine

HOME ASSIGNMENT Differentiate between oscillatory & circular

motions.Give some examples of each?How wil you differentiate between a body in

motion and a body at rest?

EVALUATION

Classify the following as motion along a straight line, circular or oscillatory motion:

Motion of your hands while running.Motion of a horse pulling a cart on a straight ro

ad.Motion of a child in a merry-go-round.Motion of a child on a see-saw.Motion of the hammer of an electric bell.Motion of a train on a straight bridge
