All 17 Terms
| | Term | Definition |
|---|---|---|
| |
Force | Push or pull |
| |
Contact force | A force that is exerted only when two objects touching |
| |
Noncontact force | No touching -- wind |
| |
What difference between balanced and unbalanced force | Equal force has a net force of zero, an unequal force allows the object to move |
| |
Newton's first law of motion | if the net force on an object is zero, an object at rest remains at rest |
| |
If an object is moving | it continues to move in a straight line with constant speed |
| |
Inertia | The tendency of an object to resist a change in its motion |
| |
A certain change in motion depends | on the object's mass |
| |
Gravity | is an attractive force that exists between all objects that have mass |
| |
Law of universal gravitation | all objects are attracted to each other with force that depends on the masses of the objects and the distance between them |
| |
What factors must be addressed when discussing gravity | More mass, the distance, the surface area |
| |
Friction | is a force that opposes the movement between two surfaces in contact. |
| |
Two outside forces on planet earth | air friction/resistance and gravity |
| |
Newton's second law | the acceleration of an object is equal to the net force exerted on the object divided by the object's mass |
| |
Newton's third law | For every action there is an equal an opposite reaction |
| |
Static friction | is the force between two surfaces in contact that keeps them from sliding when a force is applied |
| |
Friction | latin means -- to rub |
