acceleration - any chance in direction or speed a = v/t, energy - ability to do work, friction - force that opposes (goes against) motion created when surfaces rub together, gravity - the force that attract matter toward the center of the earth -  depends on mass and distance, inertia - a measure of an object's mass, "laziness", or resistance to chance its motion, kinetic energy - the energy in motion, depends on speed and mass, mass - the amount of matter/stuff in an object - measure of inertia, potential energy - stored mechanical energy due to an object's shape or position from gravity or elasticity, Newton's 1st Law - Inertia Law - "Objects at rest stay at rest; objects in motion stay in motion in straight line at a constant speed, Newton's 2nd Law - Formula: F=ma; force on an object increases if mass or acceleration increase. More massive objects are harder to move. , Newton's 3rd Law - Action-reaction - "for every force, there is always an equal and opposite force.",
