Transcript and Presenter's Notes

Title: ENERGY


1
ENERGY
  • Energy can neither be created nor conserved. 1st
    Law of Energy Conservation

2
KINETIC
  • The energy of motion
  • KE 1/2mv2 so Kinetic Energy 1/2 mass times
    velocity squared.
  • KE unit are the Joule (J) kgm2/s2Nm

3
Work Kinetic Energy Theorem
  • Wnet ?KE Net work change in Kinetic Energy
  • So Wnet 1/2mv2final - 1/2mv21iintial
