If you and a friend are going down two different slides, but the slide your friend is on is 100 ft in the air and the one you are on is 50 feet, which one of you would have more potential energy?
Your friend

You and your brother are racing a toy car and a toy truck down a ramp at your house. Your brother picks the car because he loves to go fast. You predict that the truck will win down the ramp. Explain why your prediction would be right assuming they are going the same speed and there are no other factors or forces at work?
The truck has more mass so it has more KE
What is the energy transformation in the Human body?
What is how does a pendulum represent potential to kinetic energy?
Because when it is at its highest point then it is potential energy and when it rolls down to its lowest point it is kinetic energy.
