Projectile Of Motion And It's Parameters

"An object moving with some velocity into the air at an angle 90 degrees with horizontal plane is known as Projectile."

➡Velocity an object has two components, one is horizontal component and other one is vertical component.

➡The path of an object which moves in the air in the form of a parabola is called as Trajectory.

➡A projectile has two dimensional motion, one is horizontal dimensional motion and other one is vertical dimensional motion.

➡Uniform velocity along the horizontal direction.

➡Uniform acceleration calendar vertical direction.

➡Acceleration is zero along horizontal direction.

Parameters Of Projectile:

There are 5 parameters of projectile.

1. Maximum height

2. Time of ascent

3. Time of flight

4. Horizontal range

5. Maximum range

➡1. Maximum height( Hmax):

The height at which the vertical component of the velocity becomes zero of a projectile is called as maximum height.

 

➡2. Time of ascent (ta):

Time taken by the projectile to reach the maximum height is known as time of ascent.

 

➡3. Time of flight(T):

Sum of the time of Ascent and time of Descent of a projector is known as time of flight.

➡4. Horizontal range(R):

From point of projection, the horizontal distance covered by the projectile is known as horizontal range.

➡5. Maximum range(Rm):

If the  Angle of projection is 45 degrees, then the horizontal range will become maximum, this is known as maximum range.
