Back

A force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, as mass increases, acceleration decreases if the same force is applied.

Front

What is a dependent variable?

Back

A variable that is measured in an experiment; it changes in response to the independent variable.
