0C-Changes in Forces
Changes in Force and Motion
| Term | Definition |
|---|---|
| formula for force | Force = mass x acceleration |
| formula for momentum | momentum = mass x velocity |
| formula for speed (velocity) | speed = distance / time |
| Free-Body Diagram | an illustrating showing all of the forces acting on one object |
| inertia | The tendency of an object to resist a change in motion |
| mass | how much matter is in an object |
| momentum | The product of an object's mass and velocity (mass x velocity) |
| motion | An object's change in position relative to a reference point. |
| net force | The sum of all forces acting on an object |
| newton | SI unit of force (N) |
| Newton's First Law | an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. |
| Newton's Second Law | the amount of force needed to accelerate an object is dependent on the object's mass |
| qualitative | Data in the form of recorded descriptions rather than numerical measurements. |
| quantitative | Data that is in numbers |
| reference frame | a system that uses coordinates or background objects to establish position |
| speed | The distance an object travels per unit of time |
| Symbol for Applied Force | F(A) |
| Symbol for Force of Magnetism | F(M) |
| Symbol for Force of Static Electricity | F(S) |
| Symbol for the Force of Friction | F(F) |
| Symbol for the Force of Gravity | F(G) |
| Symbol for the Force of Normal | F(N) |
| Symbol for the Force of Tension | F(T) |
| unbalanced force | forces that cause a change in motion |
| velocity | Speed in a given direction |
