Gravity • A type of force that pulls everything down to
the ground• You can’t see it but it keeps you on Earth

Weight• It is the measure of the pull of gravity• The more mass an object has the more
gravity pulls on it

It is a force happens when two objects rub together cause them to slow down
Friction

• Some materials can make the rubbing objects faster , as they make the friction lower
• Like oil

Some materials can slow down the rubbing objects , as they make the friction higher
Like rubber and sand paper
