NET FORCE |
The combination of all forced acting on object. |
|
|
SPEED |
A given distance traveled in a given time. Speed = distance divided by time. |
|
|
ACCELERATION |
A change in speed and or direction. |
|
|
VELOCITY |
The speed of an object in a given direction. |
|
|
BALANCED FORCE |
Are not moving, have a net force = 0, or move at a constant speed. |
|
|
UNBALANCED FORCE |
Are moving, changing motion, have a net force > 0. |
|
|
CONSTANT SPEED |
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed. |
|
|
LAW OF INERTIA |
An object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it. |
|
|
LAW OF ACTION-REACTION |
for every action, there is an equal and opposite reaction. |
|
|
LAW OF FORCE & ACCELERATION |
acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. |
|
|
GRAVITY |
A force that is always acting on everything on earth. |
|
|
FORCE |
Make a stationary object move, keep an object from moving at all, or change the speed / direction of an object. Measured in Newtons (N) with a spring scale. |
