Newton's Laws
Term | Definition |
---|---|
gravity | an attractive force present between any two masses |
law of inertia | resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest). It is the tendency of objects to keep moving in a straight line at constant velocity. |
net force | the resulting force determined by combining all of the forces acting on an object |
distance | the amount of space between one point and another |
mass | the amount of matter in an object |
Newton's 1st law | An object at rest will stay at rest, and an object in motion will stay in motion, unless it is acted on by a force |
Newton's 2nd law | The vector sum F of the forces on an object is equal to the mass m of the object times the object's acceleration a: F=ma |
Newton's 3rd law | When one object exerts a force on another, the second object exerts a simultaneous force with equal magnitude and opposite direction (often remembered as "every action has an equal and opposite reaction") |
acceleration due to gravity | the change in velocity caused by a gravitational force |
Gravity | an attractive force present between any two masses |
Law of Inertia | Newton's First Law. Newton's first law states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force. |
net force | the resulting force determined by combining all of the forces acting on an object |
distance | the amount of space between one point and another |
mass | the amount of matter in an object |
Newton's 1st Law | law of inertia. There are basically "two parts" to the law of inertia. The first part says that an object at rest tends to remain at rest unless it is acted on by an outside force. Simple and easy to see. |
Newton's 2nd Law |
