Time of Flight Calculator
🎯 Projectiles. Use the Time of flight formula to find time of flight, launch speed, angle θ, g: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Time of flight | s |
| Launch speed | m/s |
| Angle θ | ° |
| g | m/s² |
Worked example
Find the time of flight when Launch speed = 20 m/s, Angle θ = 45 °, g = 9.81 m/s².
Using T = 2vsinθ/g: Time of flight = 2.8832 s.
Frequently asked questions
What is the formula for Time of flight?
T = 2vsinθ/g.
What do the letters stand for, and what units are used?
Time of flight in s, Launch speed in m/s, Angle θ in °, g in m/s².
How do you calculate time of flight?
Put the values into T = 2vsinθ/g. For example, with Launch speed = 20 m/s, Angle θ = 45 °, g = 9.81 m/s², time of flight = 2.8832 s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (time of flight, launch speed, angle θ, g) and fill in the others: it rearranges the formula for you.
