Newtons first law states that an object at rest will remain at rest unless another force is acted upon it, it also states that an object in motion will stay in motion unless another force is acted upon it, this is also called Inertia.
Newtons Third law of motion means that if a force is acted upon an object there will be another force to equal or interfere with that force. Some examples are Friction and Air Resistance.
Newtons 2nd law states that the net force of an object is depended on two variables, The mass of an object and the acceleration. The equation for that is: Net force= Mass X Gravity
