 kinetic magnitude acceleration the standard unit for length scalar kind of collision in which shape does not change fulcrum at the beginning. In physics it is when time equals zero netforce Any Push or Pull averagespeed Magnitude and Direction newton a distance momentum distance divided by time inelastic mass * velocity motion energy of motion vector The standard unit of force efficiency unit of time velocity F=ma Kilograms The number and kind of atoms that make up an object weight The standard unit of mass inertia energy of position mechanical An object that can change the direction of a force or multiply forces seconds pivot point joules force * distance secondlaw force that keeps an object moving in a circle centripetal The Total distance covered divided by the time it took to travel that distance. centrifugal at right angles firstlaw one quantity increases the other quantity decreases freefall An object is moving if its position relative to a fixed point is changing. mass the change in velocity divided by time. vector quantity pressure unit of energy speed A number. Also shown as a length lever A measure of how well something uses energy. machine The force due to gravity initial The sum of the energies of position and motion conservationofenergy vector quantity for speed perpendicular Force of rubbing two surfaces together. A force of sliding force units of power power The Net force is zero. By Newton’s 2nd Law acceleration is zero potential simple machine equilibrium energy is neither created nor destroyed. elastic The ability for an object to resist changes to it’s state of motion meters The Vector sum of all of the forces acting on an object magnitude force divided by area watts work divided by time displacement kind of collision in which shape changes friction An object will continue in motion or stay at rest unless acted upon by a non-zero net force. work falling under the force of gravity only inverselyproportional fake force
