Newtons Law of Motio
Newtons Law of Motion
| Question | Answer |
|---|---|
| A force that opposes motion between two surfaces that are touching | Friction |
| An objects resistance to a change in motion. Based on mass, the more mass the more inertia. | Inertia |
| an object at rest will stay at rest, an object that is moving will stay moving unless acted on by an unbalanced force. | Newton's First Law |
| Force equals mass times acceleration (F = ma) The common sense law | Newton's Second Law |
| for every action force there is an equal and opposite reaction force | Newton's Third Law of Motion |
| Forces that are unequal in size and the direction is the same; they cause an object to move. | Unbalanced Forces |
| Forces on an object that are equal in size and opposite in direction (don't cause any change in motion) | Balanced Forces |
| states that the total momentum of objects that collide with each other is the same before and after the collision | Law of Conservation |
| The overall force on an object when all the individual forces acting on an object are added together | Net force |
| The amount of matter in an object | Mass |
| A unit of measure that equals the force required to accelerate one kilogram of mass at 1 meter per second | Newton |
| The force that pulls objects toward each other | Gravity |
| The force of gravity on an object at the surface of a planet | Weight |
| (F applied) - The force that must be applied with a push or a pull. | Applied Force |
| (F normal) - The force applied perpendicular to any surface that is in contact with an object. | Normal Force |
| The rate of change of velocity of a moving object; to speed up | Acceleration |
| Forces acting on an object that are equal in magnitude and opposite in direction | Balanced forces |
| A push or pull which changes an object's motion, direction, or the shape and size of an object; a vector quantity measured in Newtons (N) | Force |
| The force that resists the motion of one surface relative to another with which it is in contact | Friction |
| The quantity of matter contained in a body, measured in kilograms (kg) | Mass |
| Anything that has mass and occupies space | Matter |
| The resulting force after all vector forces have been added | The resulting force after all vector forces have been added |
| Forces acting on an object that are not equal in magnitude and/or direction | Unbalanced forces |
| A vector quantity describing the distance traveled by an object in a particular direction per unit time; the direction must be included for an accurate description of velocity | Velocity |
| a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing. | weight |
| the path that a moving object follows | direction |
