Solution) The gravitational potential energy is given as
GPE = Gravitational Potential × mass
The dimensions for Gravitational Potential is [L^(2)][T^(-2)]
The dimensional Formula for mass is [M^(1)]
GPE = [L^(2)][T^(-2)] × [M^(1)]
GPE = [M^(1)][L^(2)][T^(-2)]
Option(A) is correct
GPE = [L^(2)][M^(1)][T^(-2)]

Given two potential energy functions as polynomial functions of displacement in one dimension, compare the forces that lead to those potential energy functions. Please explain in simplest terms and give an example using units given.
Select all of the following statements that are true about potential energy and conservative forces. Potential energy is the energy associated with the configuration of a system. It is only possible to have potential energy if there are 2 or more objects in the system that interact with each other through internal, conservative forces. Absolute values of potential energy have no meaning: only changes in the potential energy are physically meaningful. There is only one kind of potential energy: gravitational...
Determine values for translational kinetic energy, gravitational potential energy, elastic potential energy, and total energy at 0 m, 0.2 m, and 0.4 m above the release point for a 2 kg object pulled 0.2 m downward from the equilibrium position and released from rest while attached to the end of a vertical spring with k = 50 N/m. Be aware that the spring is stretched at the release position and at the equilibrium position so you will have to use...
