Gravity and Friction

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

How does surface texture affect friction?

Back

Rough surfaces create greater friction than smooth surfaces.

Front

What happens to gravity on the Moon compared to Earth?

Back

Gravity is weaker on the Moon, so you can jump higher there.

Front

What is motion?

Back

Motion is a change in position relative to a frame of reference.

Front

What is the relationship between mass and gravity?

Back

The more mass an object has, the stronger its gravitational pull.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

How does friction affect movement?

Back

Friction can slow down or stop the movement of objects.

Front

What is an example of a situation with high friction?

Back

Walking on a rough surface like gravel.

Front

What is an example of a situation with low friction?

Back

Sliding on ice.
