Question

observe the following diagram of a rollercoaster.
at which point does the rollercoaster have maximum potential energy?
w
x
y
z

Explanation:

Potential energy (PE) in a gravitational field is given by \( PE = mgh \), where \( m \) is mass, \( g \) is acceleration due to gravity, and \( h \) is height. For the rollercoaster, the mass \( m \) and \( g \) are constant, so PE depends on height. Among points W, X, Y, Z, W is at the highest height. Thus, W has the maximum potential energy.

Answer:

W
