| 11215064945 | net force | The combination of all forces acting on an object; the overall force exerted on an object |  | 0 |
| 11215069430 | Applied Force | a force which is applied to an object by a person or another object |  | 1 |
| 11215077356 | opposing forces | forces that act in opposite directions; they are subtracted |  | 2 |
| 11215090006 | Friction | the resistance that one surface or object encounters when moving over another; work to slow down or bring object motion to stop |  | 3 |
| 11215100368 | Gravity | A force that pulls objects toward each other |  | 4 |
| 11215110840 | Weight | A measure of the gravitational force exerted on an object. |  | 5 |
| 11215119456 | balanced forces | Equal forces acting on an object in opposite directions that form a net force of zero Newtons; object motion is not changed |  | 6 |
| 11215127014 | unbalanced forces | forces acting on an object that combine and form a net force that is not zero; object motion will change in direction of greater force |  | 7 |
| 11215141676 | Inertia | The tendency of an object to resist a change in motion |  | 8 |
| 11215146780 | Newton's First Law (Law of Inertia) | An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force. |  | 9 |
| 11215154257 | Newton's Second Law of Motion (Law of Acceleration) | The acceleration of an object depends on the mass of the object and the amount of force applied; a=F/m |  | 10 |
| 11215176228 | Newton's Third Law of Motion (Law of Force Pairs) | If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. |  | 11 |
| 11215184708 | Acceleration | the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change |  | 12 |
| 11215189548 | Speed | The distance an object travels per unit of time |  | 13 |
| 11215197680 | Velocity | the speed of an object in a particular direction |  | 14 |
| 11215205170 | Motion | An object's change in position relative to a reference point. |  | 15 |
| 11215211277 | potential energy | stored energy that results from the position and/or mass of an object |  | 16 |
| 11215223900 | kinetic energy | the energy an object has due to its motion |  | 17 |
| 14441425970 | force | A push or pull exerted on an object |  | 18 |
| 14441431491 | speed formula | speed = distance/time |  | 19 |
| 14441432764 | distance-time graph (speed graph) | A visual representation of how an object's position and speed are changing over time; ARCCS (Away/Returning, Constant/Changing speed, Stopped) |  | 20 |
| 14441438093 | Speed-time graph (acceleration graph) | A visual representation of how an object's speed is changing over time |  | 21 |
| 14441450370 | F = ma Force = mass x acceleration | formula Newton derived to express the relationship between an object's mass, the force applied to it and its acceleration |  | 22 |
| 14441453498 | constant velocity | Constant speed and constant direction; forces are balanced | 23 | |
| 14441455832 | changing velocity | either speed, direction, or both are changing; acceleration and forces are unbalanced | 24 |
