Question | Answer |
Inertia | A body in motion tends to stay in motion; a body in rest tends to stay in rest |
Newton's First Law of Motion | An object that is not subject to any outside forces moves at a constant velocity covering equal distances in equal times along a straight-line path |
Vector quantity and magnitude | Consists of direction and magnitude; Magnitude is the exact quantity |
Speed and velocity | Speed = distance/time; Velocity = how quickly one's position changes (speed with direction); usually in m/s |
Forces | Outside influences that cause an object to move (mass x acceleration = kg*m/ sec^2 = Newton) |
Acceleration | How quickly velocity changes (m/sec^2) |
Inertial frame of reference | viewpoint of inertial object |
Standard unit | Units that everyone agrees on, S.I. (meters, meters/second, meters/second^2, Newtons, kilograms) |
Newton | measurement of Force, mass x acceleration, kg*m/s^2 |
Grams | measurement of mass |
Net force | Sum of all forces being exerted on an object |
Newton's Second Law of Motion | The net force exerted on an object is equal to the product of that object's mass times the acceleration (Force = Mass x Acceleration) , the acceleration is in the same direction as the net force |
Newton's Third Law of Motion | Every action has an equal and opposite reaction |
Support forces | Forces that push each other along directly on a surface |
Normal forces | Forces that are directed away from the surface (example, table exerts normal force on notebook) |
Energy | The capacity to do work |
Work | The process of transferring energy |
Conserve quantity | Energy that cannot be created nor destroyed |
Kinetic energy | Energy contained in object's motion |
Potential energy | Energy contained between or within objects |
Mechanical advantage | Process whereby mechanical device redistributes the amount of force and distance that go to performing a specific amount of mechanical work |
