# Motion and Force

## STUDENT ‘S LEARNING OUTCOME

• Demonstrate the motion and force.
• Define the motion.
• Define the force.
• Define the friction.
• Students will be able to define the effect of friction on everyday life.

### INFORMAATION FOR TEACHER

What is motion?

• The action of moving or urging (a person) to do something, that something be done;

What is force?

• Influence that produces or tends to produce a change in the motion of a moving body.

What is friction?

1. The rubbing of one body against another.
2. The resistance which a body encounters in moving over another body.

Effect of friction on everyday life;

• Friction is very important for us, due to we can walk on the ground. For stopping the moving objects, we need fricti

### Material Resources

Foot boll, book, table, toy trolley, pointer, white board, duster and textbook

### INTRODUCTION

• What is motion?

• What is force?

• What is friction?

• Effect of friction on everyday life.

### DEVELOPMENT

Activity: 1

1. In the school ground, a child kicks a football gently and then sees how far away the football.
2. Now the some child kicks the football with greater force.

Did the football move faster and farther than before?

Did greater force produce greater motion?

Activity: 2

1. A child supposed to kick a football softly and another child is supposed to stop the football from a smaller distance.
2. Now the first child kicks with greater force and the second child stops it from the same distance and then observe whether more force is required to stop the football than before? Yes! Greater force has to be applied.

Activity: 3

1. Ask a child to pull a table towards himself.
2. Now ask the same child to pull a stool or a chair towards himself. In which object, more is produced easily?   Table or  Chair

Activity: 4

Place side by side a heavy toy trolley and a small toy car. Keep a wooden plank behind them and push the plank forward forcefully.

→   Was the impact of force on both similar?

→   Which object covers larger distance?

→   Was the same force applied on both?

ASSESSMENT

Give the students following questions and ask them to tell the answer individually.

→   Was the impact of force on both similar?

→   Which object covers larger distance?

→   Was the same force applied on both?

Did the football move faster and farther than before?

Did greater force produce greater motion?

• What is motion?
• What is force?
• What is friction?
• What are the Effect of friction on everyday life?

• Write these questions on the board and ask the students to note down on their note books.
• What is motion?

( Students’ response: The action of moving or urging (a person) to dosomething, that something be done;)

• What is force?

(Students’ response:  Influence that produces or tends to produce a change in the motion of a moving body.)

• What is friction?

(Students’ response:

1. The rubbing of one body against another.
2. The resistance which a body encounters in moving over another body.
• Effect of friction on everyday life

(Students’ response: Friction is very important for us, due to we can walk on the ground. For stopping the moving objects, we need friction.)
