Question | Answer |
---|---|
Velocity | The speed and direction of a moving object |
Force | to push or pull |
net force | combination of all forces acting on an object |
balanced forces | two or more forces whose effects cancel each other out and do not change the motion of an object |
unbalanced forces | two or more forces acting on an object that do not cancel and cause the object to accelerate |
newtons 2nd 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 |
friction | force that acts to oppose sliding between two surfaces that are touching |
acceleration | the change in velocity divided by the time over which the change occured |
newtons first law of motion | states that if the net force acting on an object is so the object will remain at rest or move in a straight line with constant speed |
weight | measurment of force that depends on gravity measured in newtons |
center of mass | point in a object that moves as if all of the objects mass were concentrated at that point |
newtons third law of motion | forces that always act in equal but opposite pairs |
