Question
Energy of Motion
Darla and Rob plan an investigation to see if adding weights to a car affects its speed down a ramp. Their experimental setup consists of a ramp made of a piece of wood that is 30 cm long. The ramp is propped up on four books to give it a height at one end of 8 cm.
The setup shows 4 books, a ramp and a car at the higher end of the ramp.
Multiple Choice Question
