| Acceleration |
equals the change in velocity divided by the time for the change to take place occurs when an object speeds up,,slows down ,or turns |
| Momentum |
A measure of how difficult it is to stop a moving object equals the product of mass and volocity |
| Speed |
Equals the distance traveled by the time it takes to travel that distance |
| Velocity |
speed and direction for a moving object |
| Newtons First Law of Motion |
States that if a net force acting on a object of zero the object will remain at rest or move in a straight line with a constant speed |
| Newtons Second Law Of Motion |
States that an object acted upon by a net force will accelerate in the direction of the force and that the acceleration equals the net force divided by the objects mass |
| Newtons Third Law of Motion |
States that force always an act in equal but oppoisite pairs |
| Balanced Forces |
Two or more forces whose effects cancel each other out and do not change the motion of the object |
| Friction |
force that acts to opposite sliding between two surfaces that are touching |
| Unbalanced forces |
two or more forces acting on an object that does not cancel and causes the object to accelerate |
