Front

What is mass?

Back

The amount of matter (stuff) in an object.

Front

What is weight?

Back

The force of gravity acting on an object.

Front

What two factors affect the force of gravity between two objects?

Back

Mass and distance.

Front

How does mass affect gravitational force?

Back

As mass increases, gravitational force increases.

Front

What happens to weight as you move away from the Earth?

Back

Weight decreases as you move further from the Earth.

Front

Does mass change when you go to the Moon?

Back

No, mass stays constant regardless of location.

Front

What is the relationship between weight and gravity?

Back

Weight is the measure of the gravitational force on an object.

Front

If an object has a mass of 10 kg, what is its weight on Earth?

Back

Weight = mass x gravity = 10 kg x 9.8 m/s² = 98 N.

Front

What is the unit of weight?

Back

Newton (N).
