📚 Glossary

Newtons Laws

Three fundamental laws describing motion: (1) objects stay at rest or in motion unless acted on by a force, (2) F=ma, (3) every action has an equal and opposite reaction.

Gravity

The attractive force between masses. On Earth's surface, objects accelerate downward at approximately 9.8 m/s².

Collision Detection

The computational process of determining when two or more objects in a simulation make contact with each other.

Elastic Collision

A collision where kinetic energy is conserved — objects bounce off each other without losing energy.

Friction

A force that opposes relative motion between surfaces in contact, converting kinetic energy into heat.

Projectile Motion

The curved path of an object launched into the air, determined by its initial velocity and gravitational acceleration.

Pendulum

A weight suspended from a pivot that swings back and forth under gravity, demonstrating periodic motion and energy conservation.

Particle System

A technique using many small objects (particles) to simulate phenomena like explosions, smoke, and fluid-like behavior.

💬 Message to Learners

Every object you see — every ball that bounces, every planet that orbits, every bridge that stands — follows the same simple laws of physics. This simulator lets you play with those laws directly. Change gravity, launch particles, create collisions, and build intuition for how the physical world works. The equations are simple, but the behaviors they produce are endlessly fascinating.
