Projectile Motion
A projectile is an object upon which the only force acting is gravity. A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. Projectile motion is a predictable path traveled by an object that is influenced only by the initial launch speed, launch angle, and the acceleration due to gravity. You can try it out from where you're sitting. Pick up an object, and gently toss it up and away from you. It will rise as it flies away from you, reach a maximum height, and then start falling down to the floor. Toss a few more objects while you're at it. As long as you're not tossing pieces of paper or feathers, the projectile paths should be similar. We'll touch on this concept a bit later. Let's quickly touch on a couple key points involved in projectile motion. First, projectiles follow a predictable parabolic path, like this. Depending on how hard or how high you throw the projectile, the path could be stretched out or high and steep, but it will always be a parabolic shape. Examples -

Newton's First Law motion tends to remain in that state of motion unless an external force is applied to it.

Newton's Second Lawthe relationship between an object's mass m, its acceleration and the applied force is F = ma

Newton's Third Lawfor every action there is an equal and opposite reaction. This means that there is no
