15 cards from this deck
Ability to do work
Scalar (has magnitude, no direction)
Joule (J)
Ek=12mv2E_k = \frac{1}{2}mv^2Ek=21mv2
Quadruples the kinetic energy
Ep=mghE_p = mghEp=mgh
Energy due to position in force field
Energy cannot be created or destroyed, only transformed or transferred
Work done = Change in kinetic energy
GPE converts to KE
Remains constant (KE + PE)
Converts to heat and sound
Sources that don't get used up and can be replenished naturally
Finite sources that will be exhausted
Wind, solar, hydroelectric, wave, tidal, geothermal
