Projectile Motion Calculator
The Projectile Motion Calculator is a free physics simulation and calculation tool that helps you compute key motion parameters such as **maximum height**, **time of flight**, and **horizontal range** for a projectile launched at an angle. It uses kinematic equations to analyze **2D motion under gravity**, making it perfect for students, teachers, and researchers studying classical mechanics.
How to Use This Tool
- To use this interactive Projectile Motion Simulator, start by adjusting the launch parameters such as initial velocity, launch angle, mass, gravity, and air resistance using the sliders and dropdowns. Once set, click “Launch” to start the simulation and observe the projectile’s trajectory on the canvas. You can pause, reset, or add multiple projectiles to compare their motion. Explore different planetary gravities like Earth, Moon, or Jupiter to see how gravitational force affects range, flight time, and height. Toggle visualization options to show velocity vectors, grid lines, or trajectory comparisons for deeper analysis. The real-time charts display motion data, including velocity and trajectory graphs. For quick learning, choose from preset scenarios like Cannon Shot or Moon Launch. This tool is ideal for students and educators studying physics, motion, and kinematics interactively.

Frequently Asked Questions
Projectile motion describes the motion of an object thrown into the air, moving under the influence of gravity along a curved (parabolic) path.
It uses standard kinematic equations for projectile motion: T = (2u sinθ)/g, H = (u² sin²θ)/(2g), and R = (u² sin2θ)/g.
Yes — change the gravity value (e.g., 1.62 m/s² for the Moon or 3.71 m/s² for Mars) to simulate motion under different conditions.
Use velocity in meters per second (m/s), angle in degrees, and gravity in meters per second squared (m/s²).
Yes — it’s a free, browser-based physics calculator requiring no installation or login.
