**Projectile Given Angular Projection**

**Equation of path of projectile**− Suppose at any time*t*, the object is at point P (*x*,*y*).

*a*

_{x}is zero. The position of the object at any time

*t*is given by,

Here,

*x*

_{0}= 0,

*u*

_{x}=

*u*cos

*θ*,

*a*

_{x}= 0

[Velocity of an object in the horizontal direction is constant]

Putting these values in equation (i),

⇒

*x*=

*ut*cos

*θ*

⇒

For motion along vertical direction, the acceleration

*a*

_{y}is −

*g*.

The position of the object at any time

*t*along the vertical direction is given by,

Here,

∴

Putting the value of

*t*from equation (ii),

⇒

**This is an equation of a parabola. Hence, the path of the projectile is a parabola.**
