|---|---|---|---|---|---|
| A force that acts between systems only when one system touches another. | contact force
🗑
|
||||
| A form of friction exerted by a fluid on an object moving in relation to the fluid. | drag
🗑
|
||||
| A noncontact force exerted on a susceptible object by similar objects. | field force
🗑
|
||||
| A push or pull on a system. It may be a vector or scalar quantity. | force
🗑
|
||||
| The condition of an object accelerated by the force of gravity alone with no other forces acting on it. It can only truly occur in a vacuum. | free fall
🗑
|
||||
| A contact force that opposes the movement of objects past each other. It may be a vector or scalar quantity. | friction
🗑
|
||||
| The tendency of all matter to resist change in motion. | inertia
🗑
|
||||
| Law stating that the acceleration of a system is directly proportional to the net force acting on the system and is inversely proportional to the system's mass. | law of accelerated motion
🗑
|
||||
| Law stating that objects at rest remain at rest and objects in motion continue in a straight line at a constant velocity unless acted upon by a net external force. | law of inertia
🗑
|
||||
| Law stating that the force of gravity between two objects is directly proportional to the products of their masses and inversely proportional to the square of the distance between the centers of mass. | law of universal gravitation
🗑
|
||||
| The study of forces and how forces interact with matter, including their effects on an object's motion | Dynamics
🗑
|
||||
| Newton's third law of motion. For every external force exerted on a system by its surroundings, the system exerts an equal but opposite force on its surroundings. | Law of action-reaction
🗑
