Net force = 0 Net force = 0 - University of Iowa Physics
... • This is Newton’s second law • It is the law which explains how things move • If a net force is applied to an object it will accelerate – change its velocity • It includes the law of inertia Æ if there is no force, F = 0, then the acceleration = 0 Æ the velocity doesn’t change Æ no force is needed ...

Newton`s Laws
... Every object continues in its state of rest, or of motion in a straight line at constant speed, unless compelled to change that state by forces exerted on it. Also called Law of Inertia: things move according to their own inertia Things keep on doing what they are doing Examples: Hockey puck on ice, ...
