Step 1 of 3

Chapter 5 – Work and Energy  Work o Forces do work o Work is ascalar quantity o The work done by a force on an objec that moves it along the xis  W=F (Δx) o Work on an object gives it rgy  Work is a pe of energy transfe done with orces  It transfers ergy into/out of a system  Pushing or ulling  All energy has to be accounted for, it has to be conserved  PAPER NOTES 1 o If force and displacement point in the same direction W=F (Δx)∨W=F(d)  o If the force is at an angle  W= (
