  2. Newton’s ___ Law of Motion states that “An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. • Third • Second • First • Fourth Question 1

  3. Newton’s ___ Law of Motion states that “For every action there is an equal and opposite reaction.” • First • Third • Second • Fourth • Question 2

  4. Newton’s ___ Law of Motion states that “The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.” • Third • First • Fourth • Second Question 3

  5. A crate is at rest on the ground. What force or forces are acting on the crate? • The weight of the crate is acting downward on the crate • The ground is exerting a force equal to the weight of the crate upward • The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward • There are no forces acting on the crate Question 4

  6. An object with a mass of 11.3 kg experiences a force of 20.34 N. What is the acceleration of the object? (F = ma) A. 18.54 m/s/s B. 2.3 m/s/s C. 1.8 m/s/s D. 1.4 m/s/s Question 5

  7. Luke and Carrie are driving down a straight section of the interstate at 65 mph in Luke’s new convertible. Carrie is drinking a soda in the passenger seat. When she is done, she tosses the bottle straight up in the air. What will happen to the bottle if air resistance is neglected? • The bottle will land on the interstate in front of the car • The bottle will land on the interstate behind the car • The bottle will land in Carrie’s lap • Not enough information is given Question 6

  8. How much force is needed to accelerate a 9,760 kg F-16 fighter at a rate of 4.6 m/s/s? (F=ma) • 161,626 N • 44, 896 N • 12,471 N • 2.122 N Question 7

  9. A man drops a baseball off of the top of the Empire State building. If the action force is the pull of the Earth on the ball, then what is the reaction force? • Air resistance acting on the ball • There is no reaction force • The pull of the ball on the Earth • Gravity Question 8

  10. A water skier is pulled by a net force of 168 N and has an acceleration of 2.4 m/s/s. What is the mass of the skier? (F=ma) • 79 kg • 403.2 kg • 33.6 kg • 60 kg Question 9

  11. Rebecca is sitting at a stop light in her car when the light turns green. As she begins to push on the gas pedal the car starts to move forward. What force is accelerating the car? • The tires are pushing the car forward • Gravity • The road is pushing the car forward • The engine is pulling the car forward Question 10

  12. Potential energy is dependent on_____ • Acceleration and kinetic energy • Speed and height • Time and weight • Mass and height Question 11

  13. Energy flows through the environment in a variety of ways. All of the ways energy moves and is stored can be explained by the law of conservation of energy which states that… • Energy can neither be created nor destroyed, only transformed into other kinds of energy • Energy can be created and transformed into other kinds of energy • Energy can be transformed into other kinds of energy until it is transformed into heat and dissipates • Energy can be created and destroyed through different reactions Question 12

  14. Kinetic energy is the energy of motion. How could you determine how much kinetic energy an object has? • By finding its speed and direction • By finding its position and form • By finding its mass and speed • By finding its height and width Question 13

  15. There is a skier at the top of a ski slope. The skier has potential energy. What gives the skier his potential energy? • His efficiency • His speed • Gravity • Friction Question 14

  16. Nathan is building a deck out of 2 x 4 pieces of wood using 16 penny nails. When swinging the hammer, the end of the hammer gains speed and ____. • Kinetic energy • Potential energy • Chemical energy • Mechanical energy Question 15

  17. Jill is getting ready to push little Frank in his swing. She pulls Frank back as high as she can and then releases the swing. What is the initial transfer of energy that accelerates the swing? • Kinetic energy is converted into potential energy • Potential energy is converted into mechanical energy • Mechanical energy is converted into potential energy • Potential energy is converted into kinetic energy Question 16

  18. Which of the following is a true statement? • Energy can be destroyed, but not created • Energy can be created, but not destroyed • The total amount of energy in the universe changes rapidly • Energy cannot be created or destroyed, only changed from one form to another Question 17
