Newton's Laws

While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?

• You will lose your balance and fall over before your reach the middle of the ice rink.

• You will continue to slide across the ice until a force makes you stop or change direction.

• The force of gravity will make you keep your velocity until your friends make you stop.

• The size of your ice skates will determine how quickly or slowly you travel across the ice.

Every time your cat’s paw hits her toy string, it swings away from her. How does this demonstrate Newton’s third law of motion?

• Objects with mass, such as your cat's paw and toy string, will require inertia.

• Objects in action, such as the string toy, will experience force.

• For every motion from your cat's paw, there is unbalanced inertia from the string.

• For every action your cat makes, there is an equal and opposite reaction from the string.
