Chapter 11 Test - Force and Newton's Laws

two or more forces whose effects cancel each other out and do not change the motion of an object

• balanced force

• force

• center of mass

• net force

point in an object that moves as if all of the object's mass were concentrated at that point

• inertia

• center of mass

• fricition

• balanced force

a push or a pull

• balanced force

• net force

• force

• unbalanced forces

force that act to oppose sliding between two surfaces that are touching

• center of mass

• inertia

• weight

• friction

combination of all forces acting on an object

• net force

• balanced force

• unbalanced force

• force

states that 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 second law of motion

• Newton's first law of motion

• Newton's third law of motion

• center of mass

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 object's mass

• Newton's first law of motion

• Newton's third law of motion

• Newton's second law of motion

• center of mass

states that forces always act in equal but opposite pairs

• Newton's first law of motion

• Newton's second law of motion

• center of mass

• Newton's third law of motion

two or more forces acting on an object that do not cancel, and cause the object to accelerate

• unbalanced forces

• balanced force

• force

• net force

a measurement of force that depends on gravity; measured in newtons

• mass

• weight

• inertia

• net force
