Document Summary

Physics definition: a force is an action that causes mass to be accelerated. Isaac newton"s 3 laws object posses inertia: all these things want to accelerate a mass. A force is an action that causes a mass to accelerate. If someone is forceful they are accelerating stuff. Force can be a push, pull, a rub a pressure or a blow or impact or gravity". Newton"s (cid:885)rd law the soccer is also applying force on him. Mass is a single number, doesn"t go in any particular direction. Law #3 if a force is applied to an object, the object pushes back with the. Force and acceleration have magnitude and direction. Need to make sure its in the right direction to get the: how much force do you apply and in what direction, amount of force you are going to apply = mass x acceleration. Law #2: the force required to accelerate an object is proportional to its.
