Question

annie uses a ramp to test the speed of several cars. which of the following is true about her investigation? energy is changing the cars size energy is changing the cars position energy is changing the cars mass energy is changing the cars color

Explanation:

Step1: Recall energy - work relationship

Energy can do work, and when a car moves on a ramp, work is done on the car.

Step2: Analyze each option

• Energy doesn't change the car's size. Size is a geometric property not affected by the energy involved in this motion - related experiment.
• Energy can change the car's position. When the car moves down the ramp, its position in space changes due to the conversion of potential energy (if it was at a height on the ramp) to kinetic energy.
• Energy doesn't change the car's mass. Mass is a fundamental property and is conserved in non - relativistic scenarios like this simple ramp experiment.
• Energy doesn't change the car's color. Color is related to the car's paint and surface properties, not to the energy involved in its motion on the ramp.

Answer:

Energy is changing the car's position
