CHAPTER 6- WORK AND ENERGY
6-1: Work Done by Constant Force
scalar(dot) product between force and displacement
distance moved mutiply with force in direction of displacement
Unit=Joule(J)
1J=1Nm
6-2: Scalar Products of Two Vectors
A.B=ABCOSTHETA
Theta is angle beyween A and B
W=Fd=Fscos theta
6-4: Work Done by a Varying Force
The work are a is under the curve
Work Done by a spring force
Hooke's Law
Fs=-kx
6-4: Kinetic Energy and the Work-Energy Principle
K=1/2(mv^2)
Wnet= Delta(K)
If the net work (+), Kinetic energy increases
If the net work (-), kinetic energy decreases
Work and kinetic energy is equated, so they have same unit which is JOULES(J)
Energy= abiity to do work
