Projectile Motion Calculator
Enter launch speed, angle, and starting height to compute flight time, maximum height, and horizontal range for a projectile trajectory.
How to use this tool
- Choose a launch speed and angle for your projectile.
- Set the initial height above the landing level if needed.
- Use the flight time and range to design experiments, simulations, or game mechanics.
Projectile motion calculator for physics problems
- Quickly solve textbook-style trajectory questions without manual algebra.
- Understand how changing the angle at fixed speed affects range and peak height.
- Use the output as a reference for more complex models that include drag.
Assumptions behind the trajectory calculator
- Neglects air resistance and assumes constant gravitational acceleration.
- Assumes the projectile lands on flat ground at y = 0.
- Treats the motion in two dimensions with no wind or spin.
FAQ
- What launch angle gives the maximum range?
- With no air resistance and launch and landing at the same height, a 45° launch angle maximizes range. With different initial heights, the optimal angle shifts slightly.
- Can I change the acceleration due to gravity?
- This version fixes g at 9.81 m/s². For other planets or custom simulations, you can scale the results manually.
- What units does this use?
- Calculations assume meters, seconds, and m/s. You can convert to other units using the unit converter on ToolHop if needed.
