Gravity and Friction

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what keeps us on the ground and causes objects to fall.

Front

What is friction?

Back

Friction is a force that opposes the motion of two surfaces sliding against each other. It can slow down or stop moving objects.

Front

Which has more mass, Earth or the Moon?

Back

Earth has more mass than the Moon.

Front

What happens to objects without gravity?

Back

Without gravity, objects would float away into space.

Front

Where can you jump higher, on Earth or on the Moon?

Back

You can jump higher on the Moon because it has less gravity than Earth.

Front

What force causes a soccer ball to stop after being kicked?

Back

Friction causes the soccer ball to stop after being kicked.

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 effect of friction on moving objects?

Back

Friction slows down moving objects and can eventually stop them.

Front

How does gravity affect weight?

Back

Weight is the force of gravity acting on an object. More gravity means more weight.

Front

What is an example of friction in everyday life?

Back

An example of friction is when you rub your hands together to warm them up.
