Force
Question | Answer |
---|---|
Force | A push or pull |
Net force | The total amount of force on an object from two sources. Includes direction. |
Friction | The force opposing motion. It slows an object down. |
Balanced force | Wen net force = 0 N. No motion occurs. |
Unbalanced Force | Net force is greater than 0 N; motion occurs. |
Gravity | The force that pulls objects to the center of Earth. 9.86 m/s/s |
Newtons | Unit of measure describing force |
Weight | Mass x Acceleration of Gravity. Measured using a spring scale |
Inertia | The tendency for an object to resist a change in motion. |
Newton's First Law of Motion | Also known as the Law of Inertia. An object at rest stays at rest unless acted upon by an outside force. An object in motion stays in motion until acted upon by an outside force. |
Newton's Second Law of Motion | An object's acceleration/motion depends on the mass of the object and the force between them. |
Newton's Third Law of Motion | Each action has an equal but opposite reaction. |
