Frage Antworten
What is the equation to calculate work done? Work done = force x displacement Wd = f x s
What is gravitational potential energy? (Ep) The energy an object possesses because of its vertical position in a gravitational field
What is the equation to calculate Ep? Ep = mass x grav. field strength x height Ep = m x g x h
What other equation can be used to find Ep and why? Ep = force x displacement because Ep at a given height is equal to the work required to lift the object to that height
