Velocity versus Speed
Newton’s 2nd Law
Friction as Non-conservative Force
F = -mgj
where g is the magnitude of gravity near the surface of the earth, g=9.81m/s2.
(m=mass, v=velocity, I=moment of inertia, ω=angular velocity)
(g=gravitational acceleration near the earth’s surface, h=height)
½mvf2 + ½Iωf2 + mghf = ½mvi2 + ½Iωi2 + mghi
μ = coefficient of friction, N = normal force
