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