balanced force | two or more forces whose effects cancel each other out and do not change the motion of a object. |
center of mass | point of a object that moves as if all of the object's mass were concentrated at that point. |
force | push or pull. |
friction | force that acts to oppose sliding between two surfaces that are touching. |
net force | combination of all forces acting on an object. |
newton's first law of motion | first law of motion: a body remains at rest or in motion with a constant velocity unless acted upon by an external force |
newton's second law of motion | second law of motion: the rate of change of momentum is proportional to the imposed force and goes in the direction of the force |
newton's third law of motion | third law of motion: action and reaction are equal and opposite |
unbalanced forces | In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object |
weight | gravitational force between an object and earth. |
