Newton's 2nd law[con21] Presentation Transcript

  • 1. NEWTON’S 2 ND LAW
  • 2. Newton’s 2nd LawNewton’s 2nd Law – Acceleration of an object increases when you increase force & decreases when you increase mass.
  • 3. Equations of Inertia Distance/time=speed Final velocity – initial velocity/time=acceleration Acceleration x mass=force
  • 4. LAB
  • 5. Objective The objective of this experiment is find how the force and acceleration of an object change when you increase and decrease the mass.
  • 6. Materials 1 milk jug Water Scale Stopwatch 1 volunteer Meter stick
  • 7. Procedure Measure and mark 5 meters on the floor Weigh the empty milk jug Push the empty jug first, and start the time when you push it and stop the time when it crosses the 5 meter mark. Find the velocity of the milk jug (distance/time) Find its acceleration (final velocity - initial velocity/time) Find its force (acceleration x mass) Repeat steps 2-6 with the jug filled with water Compare the differences in force and acceleration of the two jugs
  • 8. Conclusion In this experiment we found that when you change the mass, both the force and acceleration of an object are changed. A change in any one of these factors can change the outcome.
