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?
What is the truck has more mass and therefore more kinetic energy

Trever wants his toy train to be able to make it up a hill but he does not know anything about potential and kinetic energy. Explain to Trever what he could do to to get his train up the hill. Hint: explain what he would have to do with the potential and kinetic energy
What is create a ramp to increase the potential energy which will convert to more kinetic energy when released giving it enough energy to get up the hill.
