**Projectile motion** best definition is here . Because projectile motion is easy, but conceptual. And this is best example of 2D motion. So very first, what is projectile motion and its equation equation ? . Hence it is define as, any body or particle having m mass but negligible size.

Therefore if you through any body vertically upward. Then that body moves in a straight line. Which is a vertical line. Similarly if you through a body, along horizontal line. Then again that body moves along horizontal straight line.

So both motion are straight line. But when you through a body between horizontal and vertical plan, making some angle with horizontal line. Then that body moves in a parabolic shape of path. So this is called projectile motion. And the path travel by projectile, is called **projectile motion equation.**

## What is the formula for projectile motion ?

### What is plan motion explain its importance ?

**initial velocity along x axis = ucosα****initial velocity along y axis = usinα****acceleration along y axis = -g****acceleration along x axis = 0**

#### How do you explain 2D motion ?

##### What is 2D motion explain its importance ?

**Maximum height**we know that for maximum height velocity along y axis is responsible hence use third equation v² = u² +2as

**Range**this is define as horizontal distance travel along x axis by projectile for this we know that velocity along x axis is responsible to travel distance along x axis and acceleration along x axis is zero hence again use 2nd equation s = ut +1/2at²

###### How formula is calculate for 2D- motion

###### How to solve numerical problems ?

**Numerical examples for projectile **

now sometime asked

**trajectory**this is the path of projectile which is parabolic shown above in picture we can find out this equation lets see how write the 2nd equation s = ut +1/2at² use separately for x axis and y axis for x axis x = ucos?t +0 = ucos?

for y axis y = usin?t – 1/2gt² now from x = ucos?t so t = x/ucos?

put t = x/ucos? in y equation we will get equation of trajectory.
