Newton's Third Law: Conservation of Momentum

Every action has an equal and opposite reaction. This means that when two or more objects interact, there is a reaction for both objects, equal and opposite.

This law explains what happens if we step off a boat onto the bank of a lake ... as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us face down in the water, if we aren't careful!).

Use this site to help you answer the questions about Newton's third law. Be sure to fill out your answers in your lab notebook.

Now do these experiments to learn more about conservation of motion. Be sure to record your observations in your lab notebook.
