Advanced/Notes 6.3

  1. 1. Section 6.3Kinetic EnergyWork-Energy Principle
  2. 2. Kinetic Energy How can I calculate the kinetic energy? How do I apply the Work-Energy Principle?
  3. 3. Kinetic Energy Energy is typically defined as the ability to do work Now we will only talk about mechanical energy Kinetic means moving, so we are talking about the energy during movement
  4. 4. Kinetic Energy
  5. 5. Kinetic Energy
  6. 6. Work-Energy Principle
  7. 7. Measuring Kinetic Energy Since work and kinetic energy can be equated Kinetic energy is measured in joules KE is proportional to mass KE is proportional to the square of velocity
  8. 8. Work Done?
  9. 9. Example A 145 kg baseball is thrown so that is acquires a speed of 25 m/s. (a) What is its kinetic energy? (b) What was the net work done on the ball to make it reach this speed, if it started from rest?
  10. 10. Example How much net work is required to accelerate a 1000 kg car from 20 m/s to 30 m/s?
