Using the data from Step #3 and the velocity found above, compare the gravitational potential energy of the ball at the top of the incline, with the kinetic energy of the ball just before it leaves the table. (you do not need to know the mass, just let it equal m). Is mechanical energy being conserved? Discuss. , what formula do i use to compare , ignore the rest of the question

    The question is incomplete.
    Most of the time incomplete questions remain unanswered.

    If you are looking for principles of conservation of mechanical energy, the answer is yes in most cases if there is no friction and no air resistance.

    A small ball sliding down an incline will conserve energies, exchanging between gravitational potential energy and kinetic energy.

    The general formula to use is
    at different parts of the experiment, e.g. at the top of the incline, the bottom of the incline, when it hits the ground etc. So
    Ek is kinetic energy, (1/2)mv²
    Ep is gravitational potential energy, mgh
    and h is the height measured from a given datum.
