Count the measurement of the forcemeters!

3N, 7N, 5N

This is a force that pulls everything to the ground.

Gravity

How does friction affect speed?

more friction decreases speed

Josh loves her garden slide. She finds that when she wears cotton clothes she goes faster than when she wears woollen clothes. Why?

Less friction between slide and cotton clothes than between slide and woolen clothes.

Which surface creates the most friction with skateboard? (Grass. Wood, Stone)

Grass

Mention 3 things around you that you can pull!

Your friends and teacher will check your answer.

When does friction act?

between two surfaces when they rub together

What is the unit of measurement of force?

Newton

Friction is a force that acts in an ___________ direction of movement.

opposite

Mention some workers who have to change the shape of materials. (three)

Baker, Potter, Carpenter

What are game / sport that you change the direction of a ball?

Cricket, Basketball, football (if you have different answer, your teacher will check your answer)

Does this surface smooth or rough? Why?

Smooth! Smooth surfaces have much smaller bumps.

Why is friction important?

walk, slide on a sheet of ice. brakes use friction to slow down and stop a moving car.

Mention 3 things around you that you can push!

Your friends and teacher will check your answer.

When I use elastic band, I can change its shape by .....

pulling

What is gravity?

The force that pulls objects to the ground

Does this surface look rough or smooth? Why? Friction?

Rough! It is covered with many bumps and groove which increase friction when surfaces rub together.

what's the name of this equipment?

Spring Scale

When does friction happen?

Friction takes place when object runs against each other.

When do you need to apply more force? Pushing a heavy box on ice floor or grass?

Grass! Friction also makes it harder to push objects across rough surfaces. You need more force to push an object on a rough surface than on a smooth one.

Is the friction more or less when the ground is slippery?

Less Friction. Smooth surfaces has less or no bumps and they make it easier to push objects.

When most objects with smooth surfaces rub, there is less friction. (True or False)

True

Put these in order from the smallest force to the biggest force: -a horse pulling a cart, -a girl lifting a book, -a train pulling wagons, -a bird picking up a leaf

a bird picking up a leaf, a girl lifting a book, a horse pulling a cart, a train pulling wagons.

Name the force that slows things down

Friction
