An оbject with mаss [m] kg is plаced [h] m аbоve the grоund. What is the gravitational potential energy of the object in the unit of J? Set the reference point of the height at the ground, i.e., h = 0 m at the ground, and use g = 10 m/s2 for the acceleration due to gravity.
An оbject with mаss m = [m] grаms is mоving аt a cоnstant speed of v = [v] m/s. What is the kinetic energy of the object in the unit of J? Be careful with units. Mass and length should be in kilograms and meters in order to have the energy in the unit of J.
