Newton’s 3rd law2

  1. 1. NEWTON’S 3 RD LAW Gwen Nytes
  2. 2. Newton’s 3rd LawFor every action there is an equal and opposite reaction.
  3. 3. Momentum Momentum – Force in a certain direction P=M•V
  4. 4. LABForces and Reaction
  5. 5. Objective Demonstrate momentum and how it changes when you change the variables.
  6. 6. Materials 5 volunteers; 4 to walk, 1 to time 10 meter long area Stopwatch Calculator Scale
  7. 7. Procedure Weigh and record each person and change their weight into kilograms (1 lb = 0.45359237 kg) 1 person walks at their normal pace to the 10 meter mark Time starts when they do, and ends when they reach the mark Record their time Repeat steps 2-4 with every person Calculate each person’s momentum
  8. 8. Calculations To find momentum, you take velocity x mass Velocity = distance/time + direction To find each person’s momentum:  Take 10 meters and divide it by the person’s time  Multiply that number by their weight Record each person’s momentum Compare results
  9. 9. Results You should notice that everybody’s momentum is different, even though they walked at a similar pace. This is because each one of them has a different weight. Even if you change just one variable, the outcome will be different.
