Front

What does it mean when we say 'force is a vector'?

Back

It means that force has both magnitude (size) and direction.

Front

What is the significance of the phrase 'equal and opposite'?

Back

It indicates that the forces in an action-reaction pair are always equal in strength but act in opposite directions.

How does Newton's Third Law apply to walking?

Back
