Vector quantities have magnitude and direction A + B B A R is called the resultant vector R = A + B
The Pythagorean Theorem R2 = A2 + B2 R = A + B A B
Projectile Motion Any object that is projected by some means and continues in motion under the influence of gravity and air resistance is called a projectile. The path of a projectile is called the trajectory

Circular Motion V = r r
“The greater the velocity… with which a stone is projected, the farther it goes before it falls to the earth. We may therefore suppose the velocity to be so increased, that it would describe an arc of 1, 2, 5, 10 100, 1000 miles before it arrived at the earth, till at last, exceeding the limits of the earth, it should pass into space without touching” Isaac Newton – System of the World
