Newton's Laws

Newton's 1st law states an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction, unless acted upon by unbalanced forces
Newton's First Law is also called... the law of inertia
what is inertia the tendency of an object to resist changes in motion; the more mass an object has, the more inertia it has
inertia also resists changes in... velocity, acceleration
Newton's 2nd law states the net force acting on an object causes an object to accelerate in the direction of that force
what about acceleration under Newton's 2 the acceleration of an object depends on the objects mass and the strength of the outside force acting on it. the direction of acceleration is the direction of the net force
air resistance the MAIN factor. also a type of friction
