Time of Flight of Projectile
### Formula:
$$T = \frac{2u\sin\theta}{g}$$
### Terminologies:
- T β Time of flight; total time for which projectile remains in air.
- u β Initial velocity of projection.
- ΞΈ β Angle of projection.
- g β Acceleration due to gravity.
### Usage:
- Used to calculate total time taken by a projectile to return to the same horizontal level.
