Unit 3 Chapter 16

Force and Newton's Laws

DefinitionTerm
The speed and direction of a moving object. Velocity
A push or a pull. Force
The combination of all forces acting on an object. Net force
Two or more forces whose effects cancel each other out and do not change the motion of an object. Balanced forces
Two or more forces acting on an object that do not cancel, and cause the object to accelerate. Unbalanced forces
If the net force acting on an object is zero, the object will remain at rest or move in a straight line with a constant speed. Newton's first law of motion
A force that acts to oppose sliding between two surfaces that are touching. Friction
The change in velocity divided by the time over which the change occurred. Acceleration
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 object's mass. Newton's second law of motion
A measurement of force that depends on gravity. Weight
Point in an object that moves as if all of the object's mass were concentrated at that point. Center of mass
Forces always act in equal but opposite pairs. Newton's third law of motion
