  • Q2
    Which best explains the difference between speed and velocity?
    Speed deals with upward motion, and velocity deals with forward motion.

    When a roller coaster makes sudden turns, why is a person’s body thrown from side to side?
    because of the friction of the roller coaster on its tracks
    because of the inertia of the person’s body
    because of the speed of the roller coaster
    because of the deceleration of the roller coaster as it turns

  • Q12
    When a car goes around a corner at 20 mph, why do we say it accelerates?
    The car is accelerating because it's changing direction.
    The car is accelerating because the velocity is constant.
    The car accelerates because it's going 20 mph.
    Cars accelerate when they are in motion.

  • Q13
    Three forces are acting upon the box shown in the diagram below. Assuming there is no friction between the floor and the ground, how will these forces affect the position of the box?
    Question Image
    The forces will cause the box to move to the left.
    The forces will cause the box to collapse to the ground.
    The forces will be unable to move the box in any direction.
    The forces will cause the box to move to the right.
