Laws of Motion
Term | Definition |
---|---|
First Law of Motion | Objects at rest remain at rest and objects in motion continue at a constant velocity unless acted upon by an unbalanced force. |
Inertia | The tendency of an object to not change its motion. |
Second Law of Motion | acceleration = force / mass |
Gravity | The force of attraction between all objects that depends on the mass of the objects and the distance between them. |
Weight | The force due to gravity. |
Centripetal Force | The force that causes objects to move in a curved or circular path. |
Centripetal Acceleration | The acceleration of an object because it is moving in a curved or circular path. |
Third Law of Motion | For every action force there is an equal and opposite reaction force. |
Momentum | The property of a moving object that is the product of its mass and velocity. |
Law of Conservation of Momentum | States that the total momentum of objects remains the same. |
Newton | SI unit of force |
Kilogram | SI unit of mass |
m/s/s | SI unit of acceleration |
9.8m/s/s | The acceleration due to gravity of objects near Earth's surface (neglecting air resistance). |
