    "At the top of the first and tallest hill, your potential energy is at its highest it will ever be on this ride. As you begin to descend, your potential energy decreases until it's all gone at the bottom of the hill."


    "At the bottom of the first hill, your kinetic energy is at its highest point. You're going as fast as you'll ever go on this roller coaster ride."


    Based on this evidence, what conclusion can be made

    A roller coaster is fastest at the front of the train.

    The shorter the hill the roller coaster climbs, the greater its kinetic energy.

    Potential energy is converted to kinetic energy as the roller coaster goes down the hill.

    No conclusion can be made from this evidence.
