|
Terminal Velocity |
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction of the force of gravity. |
|
|
Momentum |
A quantity defined as the product of the mass and velocity of an object
|
|
|
kinetic friction |
Friction between two objects in motion. |
|
|
tensional force |
A force transmitted through a string, rope, or wire when something is pulling on both ends. |
|
|
gravitational force |
The pulling force exerted by all objects due to their mass. |
|
|
electrical force |
Any interaction of objects due to their particles being charged |
|
|
Newton's 1st Law |
The Law of inertia; an object at rest will stay at rest and an object in motion will stay in motion until an unbalanced force acts upon it. |
|
|
Newton's 2nd Law |
F=ma
|
|
|
Newton's 3rd Law |
For every force there is an equal and opposite force
|
|
|
Free Fall |
a state of falling where no air resistance is present. |
|
|
Balanced Force |
A situation where the net forces acting on an object equal zero |
|
|
Static Friction |
The friction of two non moving objects that are in contact
|
|
|
Normal Force |
A support force exerted by anything that is holding something else off the ground. |
|
|
Magnetic Force |
an attraction or repulsion between objects because their particles have opposite or like charges. |
|
|
Projectile Motion |
The curved path that an object follows when thrown, launched, or otherise projected near the surface of the earth |
|
|
Unbalanced Force |
any time that the net force acting on an object does not equal zero it is unbalance and produces a change in motion. |
|
|
Contact Force |
A force that only occurs between two objects in contact ex. friction, applied, nomal, and tensional forces |
|
|
Air Resistance |
A type of friction that acts upon objects as they travel through the air. |
|
|
Inertia |
The tendency of an object to resist being moved, or if the object is moving, to resist a change in motion until an outside force acts upon it. |
|
|
Law of Universal Gravitation |
Any two objects in the universe exert a force on all other objects that is directly proportional to their masses and inversely proportional to square of the distance in between them. |
|
|
Frictional Force |
A force that opposes motion between two objects, its strength depends on the roughness of the objects surfaces and the force between them. |
