Back

Objects with more mass require more force to change their motion compared to lighter objects.

Front

What is a balanced force?

Back

Forces that are equal in size but 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 of an object.
