Question

using the diagram, at which point will the object have the lowest amount of * 1 point gravitational potential energy?
a
b
c
d
e

Explanation:

Step1: Recall the formula for gravitational potential energy

The formula for gravitational potential energy is \(U = mgh\), where \(m\) is the mass of the object, \(g\) is the acceleration due to gravity (\(g = 9.8\ m/s^{2}\)), and \(h\) is the height of the object above a reference level.

Step2: Analyze the height at each point

• At point \(A\), the height \(h_A=100\ m\).
• At point \(B\), the height \(h_B = 0\ m\) (assuming the lowest - level in the diagram as the reference level).
• At point \(C\), the height \(h_C = 30\ m\).
• At point \(D\), the height \(h_D\) is greater than \(h_B\) (since it is above the lowest point in the diagram).
• At point \(E\), the height \(h_E=20\ m\).

Since \(U = mgh\) and \(m\) and \(g\) are constant (for a given object in a given gravitational field), the gravitational potential energy is directly proportional to the height \(h\). The lower the height \(h\), the lower the gravitational potential energy \(U\).
