•  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?

5

•  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

 D. thermodynamic energy to dynamic energy

8

• Explain the changes in potential & kinetic energy as the golf ball moves

through A – D.

•  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

those sources of light and have discovered that many of them are not

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

 Carol and Deborah are looking at stars on a dark night and notice that two

stars next to each other are equally bright, but one is red and one is

orange. Which of the following best explains why the stars are different

colors?

 A. The stars are in different galaxies.

 B. The stars are different distances away.

 C. The stars are at different stages in their life cycles.

 D. The stars have different numbers of planets orbiting them

13

•  24

 Although the planets in our solar system have unique features, they also

have similarities. Which of the following characteristics is most similar

among the planets in our solar system?

 F. mass

 G. shape of orbit

 H. number of satellites

 I. chemical composition

14

• Explain how our current understanding of the solar system differs from an Earth

centered system.

 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.

What is the best explanation for the increase of speed of the ball?
