Upon what does the final speed of a trolley depend as it goes down a ramp? An in-depth plan and scientific prediction including variable discussion for the said experiment.

Upon what does the final speed of a trolley depend? Aim- The Aim of this investigation is to discover how certain variables affect the final speed of a trolley. I will investigate this using an elevated ramp and a trolley to down it. I will investigate the relationship between the height of a ramp (which a trolley is rolled down) and the trolley's final speed as it comes off the ramp. Hypothesis- I predict that …
