Is Anyone able to explain the relationship between kinectic energy and gravitational potential energy? **

if you mean when you have an object that is falling and gravatational potential energy is increasing whilst kinectice energy is decreasing it is because energy is never destroyed or gotten rid of simply transformed into different forms of energy so if an object is running along a flat path and has lots of kinetic energy because of its movementand no gravatational potential energy because they are on the gorund . Then say for instance theres a huge hole and this object falls down they begin to loose kinetic energy and gain gravatational because they are falling.

I havent done that topic in while so its a vague idea not to sure about it though, hope its helped a bit :D x

Thank you very much :) **

no problem, i think there is a bit more to it than that as well but im sure if you have the basic idea you will understand the questions on it :D

Thanks for your help. I will try looking into it in more detail :) **

GPE is the energy when something is up high.

KE is the energy when something is moving

When an object is falling the GPE is converting into KE because energy is conserved.

GPE= m x g x h          (i get told to take g as 10)

KE = 1/2 x m x v^2

GPE= KE in a falling object
