  1. Newton’s Second Law Physics 102 Goderya Chapter(s): 4 Learning Outcomes: 1,2,10,11,12

  2. This Chapter will help you understand: • Friction • Difference between mass and weight • Newton’s Second Law of Motion • How to apply Free Body Diagrams (FBD) • Terminal Velocity

  3. Friction

  4. Mass and Acceleration

  5. Newton’s Second Law of Motion

  6. Mass and Weight

  7. Free Body Diagram, Example

  8. Free Body Diagram, Example

  9. Example A force of 10N is applied on a box that has a mass of 3 kg. The box acquires an acceleration of 2 m/s2. What is the net force on the box and how much of that is due to friction.Ans: FN = 6N, f=-4N

  10. Example – Uniform motion • A 5.8 g bullet leaves the muzzle of a rifle with a speed of 334 m/s. What force (assumed constant) is expected on the bullet while it is traveling down the 0.77 m long barrel of the rifle?

  11. Terminal Velocity
