Question

Darcel runs the simulation for the large version of each object. What can he say in general about the energies of the objects in the simulation as they roll down the incline? (Select all that apply.)

"The total energy of the system remains constant and is equal to the gravitational potential energy of the object at the top of the incline.""The total kinetic energy of a rolling object is the sum of the rotational kinetic energy about the center of mass and the translational kinetic energy of the center of mass.""The translational kinetic energy is always greater than the rotational kinetic energy.""The potential energy of the system remains constant, and is equal to the total energy."

Explanation / Answer

The total energy of the system remains constant and is equal to the gravitational potential energy of the object at the top of the incline.
The total kinetic energy of a rolling object is the sum of the rotational kinetic energy about the center of mass and the translational kinetic energy of the center of mass."
The translational kinetic energy is always greater than the rotational kinetic energy."( in case of ring translational K.E= Rotaional K.E otherwise it is always true)
