Question

An acorn is about to fall from a tree. What type of energy does it have? A.GPE only B.KE onlyC.EPE onlyD.KE and GPE

Answer 1

We are given that an acorn is about to fall from a tree. This means that the acorn is not accelerated yet and is at a height "h" from the ground. The energy associated to ab object at a certain height is:

`U=mgh`

Where:

`\begin{gathered} m=\text{ mass} \\ g=\text{ acceleration of gravity} \\ h=\text{ height} \end{gathered}`

The energy "U" is called Gravitational Potential Energy (GPE).
