W = Fdr and is conservative if this integral is path independent (or zero for any closed curve) Kinetic Energy KE = dW = Fdr = m (dv/dt) dr = m v dv thus KE = ½ mv2 ... Define angular acceleration = / t in units of radians per second squared or rad/s2. ... reflect= refract occurs when tan B = n2 /n1 and the reflected light is polarized. ................
