|
Net Force |
a force equal to the sum of all forces applied to an object |
|
|
Inertia |
the resistance of an object to any change in its motion or direction |
|
|
Newton's First Law of Motion |
an object at rest stays at rest, an object in motion stays in motion, both unless acted upon by an unbalanced net force |
|
|
Newton's Third Law of Motion |
describes action/reaction pairs: every action has an equal and opposite reaction |
|
|
Momentum (WRITTEN OUT ON TEST) |
the quantity of motion of a moving body, measured as a product of its mass and velocity |
|
|
Law of Conservation of Momentum |
the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system |
|
|
Centripetal Force |
a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving |
|
|
Balanced Forces |
two forces acting in opposite directions on an object, and equal in size |
|
|
Conductor |
a material in which electricity, heat, or sound can travel through easily |
|
|
Insulator |
a material that reduces or stops the flow of energy |
|
|
Static Electricity |
the increase of electric charge on the surface of objects |
|
|
Static Discharge |
excess charge that is neutralized by a flow of charges from or to the surroundings |
