What is mass?

Back

The amount of matter in an object, usually measured in grams or kilograms.

Front

What is weight?

Back

The force of gravity acting on an object, measured in newtons.

How does mass affect weight?

Back

More mass means more weight because gravity pulls harder on heavier objects.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is inertia?

Back

The tendency of an object to stay at rest or keep moving unless acted upon by a force.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal, causing a change in motion.
