Projectile Motion
Visualize 2D projectile trajectories with adjustable launch angle, initial velocity, and gravitational acceleration. Observe how each parameter affects range, maximum height, and time of flight in real time.
Simple Harmonic Motion
Explore mass-spring oscillations and energy transformations. Adjust mass, spring constant, and damping to observe how frequency, amplitude, and energy interchange between kinetic and potential forms.
Circular Motion & Centripetal Force
Visualize uniform circular motion with adjustable radius and speed. See how centripetal acceleration and net force always point toward the center, and explore the role of tension, gravity, and normal force.
Torque & Rotational Equilibrium
Interactively balance forces on a rigid lever by placing masses at different distances from the pivot. Observe torque magnitudes and directions, and understand the condition for rotational equilibrium.
Buoyancy & Archimedes Principle
Drop objects of different densities into fluid of adjustable density. Observe buoyant force, weight, and net force to predict whether objects sink, float, or remain neutrally buoyant — all in 3D.
Velocity-Time Graph Explorer
Explore kinematic motion through an interactive velocity-time graph. Adjust initial velocity and acceleration to see how the v-t graph changes in real time, with a 3D ball moving along a track. Identify slope as acceleration and shaded area as displacement.
Free Body Diagram Builder
Interactively build free body diagrams for a block on a flat surface or inclined plane. Adjust mass, applied force, friction coefficient, and incline angle to see all force vectors update in 3D. Watch the net force and acceleration calculate in real time via Newton's Second Law.
Conservation of Energy
Watch a ball roll down a curved ramp as kinetic and potential energy interchange in real time. Adjust mass, release height, and friction to see how energy distributes across KE, PE, and thermal bars. Discover why total mechanical energy is constant without friction.
Elastic & Inelastic Collisions
Fire two balls toward each other and observe elastic, inelastic, and perfectly inelastic collisions. Adjust masses, initial velocities, and the coefficient of restitution. Before-and-after momentum and kinetic energy tables verify conservation laws in real time.
Pendulum Oscillation
Explore a 3D pendulum with adjustable length, mass, initial angle, gravity, and damping. Watch the θ(t) graph update live and discover that period depends only on string length and gravity — not mass. Try Moon, Mars, and Jupiter gravity settings!
Newton's Second Law
Launch a block across a 3D track and watch F = ma play out in real time. Adjust applied force, mass, and kinetic friction to see how each affects acceleration. A live v(t) graph builds as the block moves. Verify that F_net = ma with the on-screen HUD.
Friction on Inclined Plane
Drag the incline angle and watch force arrows update live: normal force, gravity components, and friction. Computes the critical angle where the block begins to slide. When the angle exceeds μₛ, the block slides with kinetic friction. Shows mg sin θ, N, and static vs kinetic friction with real-time labels.
Impulse & Momentum
Apply a force pulse to a block and verify J = FΔt = Δp. Adjust force magnitude, duration, mass, and initial velocity. The F-t graph builds in real time with the shaded area labeled as impulse. Compares impulse to change in momentum to confirm the theorem.
Spring Potential Energy
Release a spring-mass system and watch elastic PE and KE trade off perfectly. Adjust spring constant k, mass, initial displacement, and damping. Live energy bars and dual KE/PE time plots confirm Us + KE = constant. Includes the SHM period formula T = 2π√(m/k).
Work-Energy Theorem
Push a block across a surface and verify W_net = ΔKE. Adjust force magnitude, angle (−60° to +60°), mass, friction, and distance. Live KE-vs-displacement graph and a work breakdown bar chart show W_applied, W_friction, and W_net. Confirms the theorem at every step.
