|
Terminal Velocity |
the constant speed that a freely falling object eventually reaches the resistance of the medium throught which it is falling prevents further acceleration |
|
|
momentum |
the quantity of motion of a moving body,measured as a product of its mass and velocity |
|
|
kinetic friction |
the amount of retarding force between two objects that are moving relative to each other |
|
|
tensional force |
the force that is transmitted through a string,rope,cable or wire when it is pulled tight by forces acting from opposite ends. |
|
|
gravitational Force |
the force of attraction between all masses in the universe |
|
|
electrical force |
the attraction or repulsion between two particles is directly proportional to the charge of the two particles and inversely proportional to the square of the distance between them |
|
|
Newtons 1st law of motion |
An object at rest will stay at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted on by an unbalanced force |
|
|
Newtons 2nd law of motion |
The acceleration of an object is dependent upon two variables |
|
|
Newtons 3rd law of motion |
For every action there is an equal and opposite reaction |
|
|
free fall |
downward movement under the force of gravity only |
