    Quantities associated with a moving vehicle include its velocity, speed, momentum and kinetic
    energy.
    Which of these quantities will always change if the vehicle changes direction?

    A speed and kinetic energy only

    B speed and momentum only

    C speed, kinetic energy and momentum only

    D velocity and kinetic energy only

    E velocity and momentum only

    F velocity, kinetic energy and momentum only

    B) velocity and momentum are vector quantities so if the direction changes they change too

    A change in direction means it’s a vector. From the following choices, I believe the answer is E because momentum and velocity both have a magnitude and a direction while kinetic energy doesn’t have a direction.
