the sum of all the forces on an object.
if they are in the same direction, you add them. if opposite directions, subtract the smaller force from the larger one. |

| the tendency of an object to continue doing what it's doing - if its at rest, it tends to stay that way, if it's moving it tends to stay that way. Depends directly on mass |

| F=ma. If equal force is added to a set of objects, the less massive objects will accelerate more and vice versa. A larger force will be needed to accelerate a more massive object at the same rate as a less massive object. |

| For every action force, there is an equal and opposite reaction force. So, if I push down on the Earth with 80N of force, the ground will push back up on me with 80N. If the Earth is pulling an apple down with 1 N of force, the apple is pulling up on the Earth with 1 N of force. The apple would accelerate towards the Earth instead of the other way around because the Earth has more mass. |
