Force And Motion

# Force And Motion

Term Definition
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
