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 you 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
