If the greatest potential energy is 100J will the kinetic energy of the object ever reach 100J?

  • science -

    let's use a block. When a block is released from its rest place on a table, it has:
    Potential Energy = 100J
    Kinetic Energy = 0

    when a block is falling halfway down, it has:
    Potential Energy = 50J
    Kinetic Energy = 50J

    when a block is falling just before it hits the ground, it has:
    Potential Energy = 0
    Kinetic Energy = 100J
