Free Fall Simulator
The Free Fall Simulator is a free online physics tool that demonstrates how objects fall under the influence of gravity. It helps users calculate **time of fall, final velocity, and distance covered** during vertical motion, ignoring air resistance. Ideal for students, teachers, and science enthusiasts studying Newtonian mechanics or acceleration due to gravity.
How to Use This Tool
- To use this Free Fall Simulator, start by adjusting the Initial Height, Gravity, and Air Resistance sliders on the right-hand panel. These parameters determine how your object will behave during its fall. Once your desired settings are selected, click the “Start Simulation” button to begin the motion. The ball will drop from the selected height, and you can watch it fall in real time. The data boxes below display important physics values including Time Elapsed, Distance Fallen, Velocity, and Acceleration. You can pause or resume the simulation anytime using the Pause button, and click Reset to restart with new values. Experiment with different gravity strengths to simulate conditions on planets like Earth or Mars, and vary air resistance to see how drag affects motion. This tool helps students visualize free fall physics, acceleration, and the effects of gravity interactively.
Use Cases
- Simulate free fall of objects under Earth's gravity.
- Understand time, velocity, and acceleration relationships in motion.
- Compare object falls under different gravity (Moon, Mars, etc.).
- Demonstrate gravitational acceleration in classroom experiments.
- Learn basic kinematics and Newton’s laws through visualization.

Frequently Asked Questions
Free fall is the motion of an object under the influence of gravity alone, without air resistance.
The simulator uses standard kinematic equations: v = √(2gh) and t = √(2h/g) for free fall motion.
Yes — adjust the gravity value to match other planets (e.g., Moon: 1.62 m/s², Mars: 3.71 m/s²).
No — this simulator models ideal free fall without air resistance for simplicity.
Yes, it’s completely free and runs directly in your web browser.
