What is gravity?

The force that pulls objects to the ground

25

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

opposite

15

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

True

15

How does friction affect speed?

more friction decreases speed

25

This is a force that pulls everything to the ground.

Gravity

25

Name the force that slows things down

Friction

25

When does friction happen?

Friction takes place when object runs against each other.

25

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.

25

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.

25

Why is friction important?

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

25

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.

25

Does this surface smooth or rough? Why?

Smooth! Smooth surfaces have much smaller bumps.

25

Count the measurement of the forcemeters!

3N, 7N, 5N

25

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.

25

what's the name of this equipment?

Spring Scale
