  1. Common Review

  2. Make sure you review: • CIA 1-1 Review Questions • CIA 1-2 Review Questions

  3. The tendency of an object to resist a change in motion is • Gravity • Friction • Inertia • Momentum • I don’t know – I need help!

  4. The greater the mass of an object… • the lesser the gravity. • the greater the inertia. • the lesser the force. • the lesser the inertia. • I don’t know – I need help!

  5. Which will have the greatest inertia? • Bowling ball • Baseball • Tennis Ball • Ping pong ball • I don’t know- I need help!

  6. Your parent presses the car brakes while driving …which of the following describes your motion? • Your body moves backward • Your body does not move • Your body moves forward • Your body remains at rest • I don’t know – I need help!

  7. Newton’s Second Law states that… • Objects in motion stay in motion. • Objects at rest stay at rest. • If a net force is applied onto an object, it will accelerate. • For every action there is an equal and opposite reaction. • I don’t know – I need help!

  8. You are having difficulty pulling a pile of books in a wagon. What would be the best way to increase the acceleration of the wagon? • Remove some books from the wagon. • Add some books to the wagon. • Remove the wheels from the wagon. • Have a friend help you get on an exercise program • I don’t know – I need help!

  9. A person pushes a 10kg shopping cart down the isle. The cart accelerates at a rate of 2m/s2. How much force did he exert on the cart? • 5 N • 12 N • 20 N • 5 kg • I don’t know – I need help!

  10. 40 N 30 N What will happen to this object if the forces are applied? • The object will accelerate to the left. • The object will accelerate to the right. • The object will stay at rest. • The object will not accelerate. • I don’t know – I need help!

  11. Newton’s Second Law states that… • Objects in motion stay in motion. • Objects at rest stay at rest. • If a net force is applied onto an object, it will accelerate. • For every action there is an equal and opposite reaction. • I don’t know – I need help!

  16. Which of the following describes Newton’s Third Law of Motion? • Objects at rest stay at rest. • If you apply a net force, acceleration will occur. • Objects in motion stay in motion. • For every action there is an equal and opposite reaction. • I don’t know – I need help!

  17. A space shuttle is being launched. Identify the action force. • Release of Gas • Gravity • Lift-Off • Weight of Shuttle • I don’t know- I need help!

  18. How does Newton’s 3rd Law apply to your ability to walk? • Ground pushes down and your foot pushes up. • Your foot pushes down with a greater force and the ground pushes back with a lesser force. • Your foot pushes down on the ground and the ground pushes back with an equal force. • I don’t know, I need help.
