First Law of Motion
An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.
Ready...
What forces cause an object to move or to stop moving?
What is Net Force?
A thrown ball moves in a horizontal direction. The force of gravity pulls it downward toward the ground. We call this Projectile Motion.
One "Newton" is the amount of force needed to cause a 1-kg mass to accelerate at a rate of 1 meter per second for each second of motion.
N = 1 kg X (1m/Sec2)
They say an object at rest to have 0 net force. An object that has force applied to it will move in the direction of the force. Recall velocity is the speed and direction of an object.
