Question

A student wants to design an experiment to study the transformation of mechanical energy. Which object can be used to investigate how gravitational potential energy transforms into kinetic energy?(1 point)

a spring

a flat race car track

a slide

a rug

Answer 1

Answer: I think it would be a spring

Explanation: a rug, a slide, and a race track would all have friction and friction is not a conservative force which wouldn’t qualify for mechanical energy.

That’s my guess I’m not very good at this stuff though

Answer 2

I guess it’s the 3rd one
