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 and therefore more kinetic energy
