Projectile motion: A kind of motion that is experienced by an object when it is projected near the Earth's surface and it moves along a curved path under the action of gravitational force.
- When a particle moves in projectile motion, its velocity has two components.
- vertical component (u sinθ)
- horizontal component (u cosθ)
- There is no acceleration or forces in the horizontal direction so the horizontal component of velocity (u cosθ) will remain constant.
The range of the projectile,
R = u cos θ × t
Whereas the time of flight is the total time for which the projectile stayed in the air.
Time of Flight:
The time of flight of projectile motion is the time from when the object is projected to the time it reaches the surface.
- The mathematical expression of the time of flight is -
The angle of projection = θ, Initial velocity = u, Gravitational acceleration = g, Time of flight = t, Range of projectile = R
Maximum height:
It is the maximum height from the point of projection, a projectile can reach
- The mathematical expression of the maximum height is -
Horizontal Range:
The range of the motion is fixed by the condition y = 0.
- The mathematical expression of the horizontal range is -
Where R is the total distance covered by the projectile.
