INTRODUCTION“Good morning students, take your seat please.”

Are you all ready for the lesson?

So alright then, today we shall start new chapter i.e chapter 3, force. Under this topic you will learn a) Definition of forceb) Examples of different kinds of force c) Effects of force(Teacher writes the topic ‘force’ on the

board)

“Good morning sir. Thank you sir”

Yes sir.

Student listens.

6minLesson development

Activity IOkay, before we start our lesson can anyone standup and lift your textbook?

Now can anyone tell us how could he lift the book easily?

Good. So that effort is know as ‘Force’Now can anyone define in your own words?

Good! any other definition?

Response quickly.

He had applied some effort in order to lift the book.

Force is the effort that can bring change in size, shape and direction of the body.Gives the similar definition.

So, a force is that physical cause which changes (or tends to change) the dimensions or the state of rest or the state of motion of body.

Listen now! We come across different kinds of forces in nature. Some of these forces are:1. Muscular force: force applied as

push, pull or stretch. E.g. Stretching of rubber.2. Mechanical force: force applied

by machine. E.g. Engine of the vehicle.

Students are let to repeat the definition .

Student listens.

3. Frictional force: force applied when two things are brought into contact. E.g. Rubbing stone against wall.4. Gravitational force: the pull exerted by the earth. E.g. Falling of an apple.5. Magnetic force: force exerted by magnet. E.g. Attraction of nails by magnet.6. Electrical force: force exerted by charge. E.g. Attraction of pieces of paper by a scale rubbed on a hair.Am I clear to you? Yes sir.

4mins Activity IINow we are going to look the effects of the force. There are three effects of force. They are:1. It can bring change in dimensions.

E.g. in a cycle pump, when the piston is lowered the air is compressed to occupy less volume.

2. Force can start or stop the motion. E.g. the push exerted by a broom to the rubbish.

3. Force can change the speed or the direction of the motion or both. E.g. when more speed is applied on the pedal of a cycle its speed increases.

Did I made you clear? Yes sir.

3mins ClosureSo to end our lesson let us recall what we have learned today. What is force? (points to one of the student)

Good! Can anyone tell us what are the different kinds of the forces?

Force is that physical cause which changes or tends change the dimensions or the state of rest or the state of motion of a body.

The different kinds of forces in nature are:1. Muscular2. Mechanical3. Frictional4. Gravitational5. Magnetic 6. Electrical forces.

Excellent! What are the effects of the forces? [ points to the one of the students ]

Good! When you reach home revise once again. I will ask you question tomorrow.Thank you.

The effects of the forces are:

1. Force can bring change in dimensions.

2. Force can start or stop the motion.

3. Force can change speed or the direction of the motion or both.

Thank you sir.
