Force and Motion Cheat Sheet by starfruits via cheatography.com/47283/cs/13825/ Vocab Motion distance from another object changes, change in position Reference point place or object used for comparison Speed the time it takes something to move a distance Velocity speed and direction Vector quantity size/m ​agn ​itude and direction Scalar quantity size/m ​agn ​itude Constant speed a speed that stays the same through the distance Instantaneous speed speed at any instant Distance the length of all parts/ ​between two points Displa ​cement the distance from start to end, the overall change in position and a direction Accele ​ration the rate at which velocity changes Equili ​brium all the forces of an object balance out Inertia the property of an object that it resists to change in motion Mass amount of matter in an object Momentum mass in motion Important Inform ​ation Force -a push or a pull -results in two or more objects intera ​cting with each other -all forces have magnitude and direction -measured in Newtons (N) Acceleration -increase speed: speed up -decrease speed: slow down, decele ​ration -change direction Important Inform ​ation (cont) Speed (dista ​nce ​-time) graphs -point on graph= location of an object from 0 at a particular time -straight slope= ​con ​stant speed -steeper slope= ​faster -horiz ​ontal line=no movement -curved line=a ​cce ​ler ​ation Veloci ​ty-time graphs -point on graph= ​speed of object at a particular time -straight line=c ​onstant accele ​ration -steeper slope= ​greater accele ​ration -horiz ​ontal line=c ​onstant speed Formulas Speed distance / time Distance speed x time Time distance / speed Average speed total distance / total time Accele ​ration final velocity - initial veloci ​ty/time Mass force / accele ​ration Force mass x accele ​ration Accele ​ration force / mass Momentum mass x velocity Newton's Laws of Motion Law 1 An object at rest will stay rest, and an object in motion will stay in motion until a force acts on it. Law 2 Force causes accele ​ration, while mass resists accele ​ration. Law 3 Any action has an equal and opposite reaction. By starfruits cheatography.com/starfruits/ Published 6th December, 2017.
