Question

multiple answer 1 point
which of the following factors determine the amount of gravitational potential energy an object has? (select all that apply)
gravity
velocity
mass
friction
height

Explanation:

Step1: Recall gravitational potential energy formula

The formula for gravitational potential energy is \(U = mgh\), where \(m\) is mass, \(g\) is acceleration due to gravity, and \(h\) is height.

Step2: Analyze each option

• Height (\(h\)): Directly in the formula \(U = mgh\), so it affects gravitational potential energy.
• Friction: Not in the \(U = mgh\) formula. Friction affects kinetic energy (due to work - energy theorem \(W_{friction}=-\Delta K\)) but not gravitational potential energy.
• Mass (\(m\)): Directly in the formula \(U = mgh\), so it affects gravitational potential energy.
• Velocity: Velocity is related to kinetic energy (\(K=\frac{1}{2}mv^{2}\)), not gravitational potential energy.
• Gravity (\(g\)): Directly in the formula \(U = mgh\), so it affects gravitational potential energy.

Answer:

Height, Mass, Gravity.
