The back of the skateboard will move upward.

Front

Why is a person propelled forward when a car suddenly stops?

Back

An object in motion stays in motion until an unbalanced force acts on it.

Front

According to Newton’s 2nd Law of Motion, what will happen to an object if the pushing force is doubled?

Back

The acceleration of the object will also double.

Front

Which of the following best explains Newton’s 2nd Law of Motion?
