Forces and Motion
| Question | Answer |
|---|---|
| Acceleration | is a measure of the change in velocity during a period of time |
| Force | is a push or a pull on an object |
| Contact force | is a push or a pull on one object by another object that is touching it |
| Newton's second law | states that the acceleration of an object equals the net force on an object divided by the object's mass |
| Friction | is a force that resists the sliding motion of two surfaces that are touching |
| Free body diagram | is a simple model to understand systems of objects with any amount of applied force |
| Net force | is the sum of all the forces acting on an object |
| Newton's first law of motion | states that an object in motion will stay in motion,and an object at rest will stay at rest unless acted on by a force |
| Inertia | An object's ability to resist any change in motion. |
| Non-contact force | es una fuerza que un objects puede ejercer sobre otro sin estar con contacto. |
| Gravity | es una fuerza de atraccion que existe entre todos los objetos que tienen masa |
| FIeld | es una region en el espacio que posee una magnitude fisica( por ejemplo,una fuerza) en cada Punto. |
| Weight | El peso es la fuerza de gravedad ejercidad sobre un objeto. |
| Newton's 3rd Law | cuando un objeto aplica fuerza fuerza sobre otro,El segundo aplica |
| position | a place where someone or something is located or has been put |
| Reference point | a basis or standard for evaluation, assessment, or comparison; a criterion. |
| vector | es una cantidad que tienen direccion y magtitud. |
| Velocity | Es la medida de distancia que un objeto en una cantidad determinada de tiempo |
| Speed | es la velocidad y la direccion que un objeto en movimiento |
| Displacement | the moving of something from its place or position. |
| Motion | the action or process of moving or being moved. |
| Inelastic Collision | the action or process of moving or being moved. |
| Elastic collision | cuando los objetos colicionan y se pegan |
| Normal force | empuja perpendicular a la superficie del objeto |
| Force pair | son las fuerzas que dios objetos ejercen entre si |
