Front

Definition of mass

Back

Mass is how much matter an object has.

Front

Weight dependency

Back

An object's weight depends on the strength of gravity.

Front

Weight on Earth compared to mass

Back

The weight of an object on Earth is approximately 10 times greater than its mass.

Front

Mass change in the solar system

Back

The mass of an object does not change on other bodies in the solar system.

Front

Friction definition

Back

When two surfaces rub together, you get the force of friction.

Front

Direction of friction

Back

The force of friction always acts in the opposite direction to the direction of motion.
