  •  Leah is using a 3.4meter (m) ladder to paint the

    exterior of her house. Leah has a mass of 50kilograms

    (kg). The acceleration due to gravity is equal to 9.8

    meters per second squared(m/s²). What force, in

    Newton's (N) does Leah exert on the ladder when she is

    standing on it?

  •  Calculate the mechanical energy of an object being

    thrown through the air. The object has 28 Joules (J) of

    potential energy due to its position above the ground,

    and 41 Joules (J) of kinetic energy due to its motion.

    Mechanical energy = potential energy

    +

    Kinetic energy

    6

  •  If a pendulum is swinging back and forth, energy is

    being converted from to another. Kinetic energy is the

    energy of motion…so why does the pendulum slow down

    and eventually stop if energy is conserved?

    7

  •  Gail’s cross-country coach advised her to eat well-balanced meals in order

    to have plenty of energy for their upcoming track meet. To which

    transformation of energy is Gail’s coach referring?

     A. heat energy to mechanical energy

     B. mechanical energy to electrical energy

     C. chemical energy to mechanical energy

  •  For thousands of years, astronomers believed that all the objects in the

    night sky that had produced their own light were individual stars. Since

    the invention of the modern telescope, we have been able to examine

    individual stars. Which sources of light have been found to be collections

    of billions of stars and not individual stars?

     A. comets

     B. constellations

     C. galaxies

     D. meteors

     Sam drops a rubber ball from the top of a staircase to his friend on the

    bottom of the staircase. The speed of the ball increases as it gets farther

    away from Sam’s hand.
