LECTURE 6: WORK AND ENERGY
Work Done by a Constant Force
W=Fdcosθ
Unit= Joule, J
1J=1N.m.
no work if force perpendicular to the displacement
Solving work problem
Find the work done by a specific force
Apply Newton's Laws to determine unknown forces
To find the net work, either
find the net force and then find the work it does
find the work done by each force and add
Choose a coordinate system
Draw a free body diagram
Scalar Product of Two Vectors
A.B=ABcosθ
w=F.d=Fdcosθ
Kinetic Energy and The Work-Energy Principle
Wnet,∆K=1/2mvfinal^2-1/2mvinitial^2
Kinetic Energy, K=1/2mv^2
Work Done by a Varying Force
Work=area under the graph
Work Done by a Spring Force
Fs=-kx
