This is a force that pulls everything to the ground.

Gravity

Name the force that slows things down

Friction

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.

Why is frction helpful?

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

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.

When does friction happen?

Friction takes place when object runs against each other.

What happens when you kick a ball on the grass?

roll, slow down, stop. Friction between the ball and the grass slows the ball. Friction causes the ball to slow and stop. If there were no friction, the ball wo

Does this surface smooth or rough? Why?

Smooth! Smooth surfaces have much smaller bumps.

Is the friction more or less when you rub your book against a towel?

More friction. Because towel has a rough texture. More bumps make the object hard to move.

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.
