|
|

unbalanced forces |
|
|
forces that cancel each other out when acting together on a single object |
balanced forces |
|
|
the speed and direction of a moving object |
velocity |
|
|
a force that opposes motion of an object in contact with a surface |
friction |
|
|
the combined effect of all the forces acting on an object |
net force |
|
|
a force of attraction that exists between any objects with mass |
gravity |
|
|
Newton's First Law |
an object at rest tends to stay at rest unless changed by an outside force an object moving in a straight line at constant speed tends to keep moving that way unless acted upon by an outside force |
|
|
Newton's Second Law |
force= mass times acceleration acceleration is affected by mass and forceee |
|
|
Newton's Third Law |
for every action there is an equal or opposite reaction. (unequal reaction) |
