= Energy = The capacity to do work or transfer heat == Types == * Potential - Stored energy * Kinetic - Energy due to motion - KE = (0.5)mv^2 * m = mass * v = velocity * Chemical - Stored in substances == Measurement == KE is measured in Joules * 1 J = a 2kg object with velocity of 1m/s == Conservation of Energy == Energy is conserved when converting. Energy is neither created nor destroyed. [[index]]
