    30 seconds
    Q.

    When figuring GRAVITATIONAL POTENTIAL energy, what matters more?

    answer choices

    speed

    height

    amount of fur

  • Question 8
    30 seconds
    Q.

    Which has more GRAVITATIONAL POTENTIAL energy and WHY? (Choose the BEST explanation!)


    A roller coaster car at the top of a hill

    OR

    a roller coaster car at the bottom of the hill.

    answer choices

    The car at the top because it is not moving, so it has more potential energy.

    The car at the top because it is higher off the ground, so it has more GPE.

    The car at the bottom because it is going faster.

    The car at the bottom because it can't go any lower.

  • Question 9
    30 seconds
    Q.

    Which has more KINETIC energy and WHY? (Choose the BEST explanation!)


    A roller coaster car at the top of a hill

    OR

    a roller coaster car at the bottom of the hill.

    answer choices

    The car at the top because it is not moving, so it has more potential energy.

    The car at the top because it is higher off the ground, so it has more GPE.

    The car at the bottom because it is going faster.

    The car at the bottom because it can't go any lower.

  • Question 10
    30 seconds
    Q.

    What is the mechanical energy of a system?

    answer choices

    just potential energy

    just kinetic energy

    the sum of the potential and kinetic energy

    kinetic energy minus potential energy

  • Question 11
    30 seconds
    Q.

    A plane flying above the ground has what energy?

    answer choices

    Only GPE because it is high

    Only KE because it is moving

    GPE and KE because it is off the ground and moving
