Matter: matter anything that has mass and occupies space, weight pull of gravity on mass, 3 states of matter, solid definite shape and volume, liquid changeable shape; definite volume, gas changeable shape and volume. Energy: capacity to do work or put matter into motion, types of energy, kinetic energy in action, potential stored (inactive) energy, energy can be transferred from potential to kinetic energy. Energy form conversions: energy may be converted from one form to another, energy conversion is inefficient, some energy is "lost" as heat (partly unusable energy)
