Common questions
What is the Projectile Time of Flight formula?
Projectile Time of Flight is written T = 2v₀ sin(θ)/g. Total time a projectile spends in the air. It belongs to Mechanics, under Kinematics.
What are the units in T = 2v₀ sin(θ)/g?
In SI units, T is time of flight, measured in s; v₀ is initial velocity, measured in m/s; θ is launch angle, measured in rad; g is gravitational acceleration, measured in m/s².
How is the Projectile Time of Flight formula derived?
Time to reach max height is t = v₀sinθ/g. Total time is 2t. The result is T = 2v₀ sin(θ)/g.
