Suppose we have an object <br />And object has an initial velocity <br />Let us decide the direction be anywhere <br />If then that object is allowed to travel <br />Freely but under gravity. <br />The same motion is called projectile motion <br /> <br />In case of projectile motion, <br />Accelaration due to gravity is constant <br />The effect of air resistance is negligible <br /> <br />It is the two dimensional motion <br />Can be regarded as simultaneous superposition of two motions. <br />One horizontal with velocity "u"cos theta and accelaration=0. <br />Other verticle with velocity "u" sin theta and accelaration=-g.<br /><br />Vizard Dhawan<br /><br />http://www.poemhunter.com/poem/projectile-motion/
