Select all true statements about mechanical energy

• Mechanical energy is the sum of the potential and kinetic energy of an object.

• Mechanical energy is determined by an object's motion and position.

• Mechanical energy is the product of the potential and kinetic energy of an object.

• Mechanical energy is determined by an object's motion ONLY.
