Gravity is a force that pulls everything down to the ground and keeps objects on Earth, though it cannot be seen. Weight measures the strength of gravity's pull on an object, with more massive objects experiencing a stronger pull. Friction is the force that occurs when two objects rub together, causing them to slow down, and can be increased or decreased depending on the materials, with oil reducing friction and rubber or sandpaper increasing it.

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

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

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

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

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

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