  1. Chapter 12 TEST Review Newton’s First/Second Law Inertia Gravity Projectile Motion Newton’s Third Law Momentum

  2. Newton’s First Law • Applies to what kind of objects ( moving, at rest, or both )?

  3. Inertia • What is it? • Similar to what physical property?

  4. Newton’s Second Law • What is it? • Example: what force is needed to make a 2 kg object reach an acceleration of 5 m/s2?

  5. Newton’s Second Law • Example: A force of 20 N is applied to a 2 kg object. What is its acceleration?

  6. Newton’s Second Law • Example: A force of 20 N is applied to accelerate an object to 2 m/s2. What is the object’s mass?

  7. Mass and Weight • Are they the same? Why?

  8. Acceleration of Gravity • g = 10 m/s2 • Pulls on any object not supported from beneath • Causes objects to orbit Earth

  9. Weight • What is the weight of a 5 kg object (acceleration of gravity is 10 m/s2)?

  10. Gravity • Know how gravity can be change by changing mass or distance involved • Gravity _________ with increased mass? (increase/decrease) • Gravity _________ with increased distance? (increase/decrease)

  11. Projectile Motion • Examples will be given, you determine if it counts as projectile motion or not

  12. Newton’s Third Law • What is it?

  13. Momentum • A 2 kg object is moving at 5 m/s towards the East. What is its momentum?

  14. Momentum • A 2 kg object is at rest. What is its momentum?
