At its highest point, the pendulum is 1.2m above the ground and as a gravitational potential energy of 62J. If the gravitational potential energy is 10J at its lowest point, what is the pendulum's kinectic energy at this point?

  • science -

    The difference in GPE from the highest point to the lowest pont=KE at bottom

  • science -

    the kinetic energy is zero, because when it is at the bottom it is not accelerating
