What is an example of an unbalanced force?

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a balanced force?

Back

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

Front

How does friction affect motion?

Back

Friction opposes motion and can cause an object to slow down or stop.
