**The projection motion is one kind of motion. A projectile is an entity thrown into the air or into space. A trajectory is a curved direction with which the projectile is moving. In a horizontal direction with constant velocity, the free-fall motion of any object is known as projectile motion.**

** **

**Projectile Motion Formula or trajectory formula is formulated as**

**Where,****Vx = the velocity (along the x-axis)**

**Vxo = Initial velocity (along the x-axis)**

**Vy = velocity (along the y-axis)**

**Vyo = Initial velocity (along the y-axis)**

**g = acceleration due to gravity**

**t = Time taken**

**Equations related to the projectile motion is given as**

**Where****Vo = Initial Velocity****sin θ = Component along the y-axis****cos θ = component along the x-axis**

**The formula of projectile motion is used to calculate the velocity, distance and the time observed in the projectile motion of the object.**

**Projectile Motion Solved Example**

**Problem 1: Jhonson is standing on the top of the building and John is standing down. If Jhonson tosses a ball with velocity 30 m/s and at the angle of 700 then at the time 3s what height will the ball reach?**

**Answer:**

**Given:**

**Vyo = 30 m/s**

**Δ t = 3s**

**The Vertical velocity in y-direction is expressed as**

**Vy = Vyo sin 70o**

**Vy = 30 sin 70**

**Vy = 23.22 m/s**
