Work and Energy
Kinetic Energy and Work-Energy Principle
Mechanical energy
Ability to do work
Kinetic Energy
K=(1/2)mv^2
Work-Energy principle
Net work done on object = change on kinetic energy
Work Done by a Varying Force
Numerical Integration
Work done by a spring force
F=-kx
W=(1/2)kx^2
Work Done by a Constant Force
Distance moved multiplied by the component of the force in the direction of displacement
W=Fd cos a
SI Unit: J
Scalar Product of Two Vectors
Scalar Product (Dot Product)
Vector A dot Vector B = AB cos a
