How to Use the Projectile Motion Calculator
This calculator computes key projectile motion parameters using standard physics equations. All inputs are in metric units (meters, seconds, m/s²).
- Enter Initial Velocity (m/s): A positive number (e.g., 20).
- Enter Launch Angle (degrees): Between 0 and 90 (e.g., 45).
- Enter Initial Height (m): Non-negative (default 0).
- Enter Gravity (m/s²): Positive (default 9.81 for Earth).
- Click "Calculate" or press Enter.
Results shown: Maximum Height, Range, Time of Flight, and Impact Velocity. A formula breakdown explains each step.
Tip: Use 9.81 for Earth, 1.62 for Moon, or 3.71 for Mars.

Frequently Asked Questions
Projectile motion describes the motion of an object launched into the air under the influence of gravity alone (ignoring air resistance). It follows a parabolic trajectory.
Maximum height is calculated using the formula: h_max = h0 + (v0y^2)/(2g), where v0y is the initial vertical velocity component and g is gravity.
All inputs and outputs use SI units: meters for distance, meters per second for velocity, seconds for time, and degrees for angle.
