Foldable INSTRUCTIONS!! Newton’s Law: Drawing of Demo: Answer to demo questions:

Newton’s First Law of Motion An object will remain at rest or move in a straight line with constant speed unless it is acted upon by a force.

Newton’s First Law of Motion at the Space Station

STOP! … Quick demo! Do the eggs react the same or different when the force is applied? If they react differently, explain what causes a different reaction. On your foldable… draw a picture demonstrating what occurred to the eggs using Newton’s 1st Law of Motion.

Newton’s Second Law of Motion An object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration equal to the force divided by the objects mass. F = m x a

Newton’s Second Law of Motion at the Space Station

STOP!! … Quick demo! Do the marshmallows fly at the same distance? If they do not, explain why the marshmallows land at different distances? On your foldable, DRAW a picture demonstrating what occurred using the marshmallow tubes using Newton’s 2nd law of motion.

Newton’s Third Law of Motion For every action, there is an equal but opposite reaction.

Newton’s Third Law of Motion at the Space Station

STOP!! … Quick demo! Explain the direction of the forces that are acting on the person on the scooter. In your foldable, DRAW a picture demonstrating what occurred to the person on the scooter using Newton’s 3rd law of motion.
