Front

What is a force?

Back

A force is a push or a pull that can cause an object to move, stop, or change direction.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.
