Physics trolley investigation

olley. I think this because at the top of the ramp the trolley will have its greatest gravitational potential energy (GPE) this is because it is at its highest point. If GPE = mass x gravity x height ... the same. At the bottom it will have its greatest kinetic energy. This is because the gravitational potential energy (GPE) gradually turns into kinetic energy (KE) as it falls. This happens because en ...
