1st Quarter Vocabulary
| Term | Definition |
|---|---|
| Applied Force | A force which is applied to an object by a person or another object |
| Opposing Forces | Forces that act in opposite directions |
| Gravity | A force that pulls objects toward each other |
| Weight | A Measure of the gravitation force exerted on an object |
| Unbalanced forces | Forces acting on an object that combine and forma a net force that is not zero |
| Inertia | The tendency of an object to resist a change in motion |
| Newton's First Law | An object in motion(or at rest) will tend to stay in motion ( or rest) until it is acted upon by an outside force |
| Newton's Second Law | The acceleration of an object depends on the mass of the object and the amount of force applied. F=MA |
| Newton's Third Law | For every action there is an equal and opposite reaction |
| Acceleration | the rate at which velocity changes over time |
| Speed | The distance an object travels per unit of time |
| Velocity | The speed of an object in a particular direction |
| Motion | An objects change in position relative to a reference point |
| Potential Energy | stored energy that results from the position and/or mass of an object |
| Kinetic Energy | the energy an object has due to its motion |
| Force | A push or a pull |
| Constant Velocity | Constant speed and direction |
| Balanced Force | Two forces in opposite directions. No Motion |
| Friction | the force between objects that resists motion |
| Newton | A measurement of force |
| Magnitude | The strength or size of an object |
| Mass | The total amount of matter in something |
| Net Force | Total of all the forces acting upon an object |
| Vector | An quantity that has a magnitude and direction |
| Distance | The amount traveled from a certain spot |
| Aerodynamics | Relating to the forces of air in motion |
| Thrust | The reaction force that propels a rocket forward |
| Propulsion | the Action of driving or pushing forward |
| Center of Mass | Point in a object that moves as if all of the object's mass were concentrated at that point |
| Streamlined | A smooth shape designed to decrease resistance |
| Drag | resistance by friction from air or water |
| Coefficient of drag | the capability of a particular object to create drag |
| Momentum | The product of an object's mass and velocity |
