Classical Mechanics Track

14 hands-on mechanics labs, in a learning order. Each one is interactive — you drag, predict, and watch the physics play out — not a video, and every number is exact.

New to mechanics? Work top to bottom — vectors and forces first, then energy, momentum, and machines. Revising for an exam? Jump to any topic. Every lab has a predict-it-yourself mode and shows the governing equation live.

Vectors & Kinematics

The language of motion: how quantities with direction combine.

1

Vector Addition Simulator

Beginner

Drag two vectors and watch the resultant — why |A+B| ≤ |A|+|B|.

2

Relative Velocity Simulator

Intermediate

Cross a flowing river; aim upstream to cancel the drift.

Forces & Newton's Laws

What makes things speed up, slow down, or turn.

3

Newton's Second Law Simulator

Beginner

Push a cart: a = F_net/m, with a live velocity–time graph.

4

Inclined Plane & Friction Simulator

Intermediate

Block on a ramp — the critical angle arctan(μs) that starts a slide.

5

Circular Motion Simulator

Intermediate

Whirl an object; cut the string and it flies off tangent, not outward.

Energy & Work

Energy is conserved, traded, and transferred by forces.

6

Work & Power Simulator

Beginner

W = F·d·cosθ — why a perpendicular force does zero work.

7

Energy Conservation Simulator

Intermediate

KE ↔ PE on a half-pipe; friction bleeds energy into heat.

8

Hooke's Law Simulator

Intermediate

Springs: F = kx, elastic energy, and series-vs-parallel stiffness.

Momentum & Rotation

Conserved quantities of straight-line and spinning motion.

9

Impulse & Momentum Simulator

Intermediate

J = F·Δt = Δp — how crumple zones cut the peak crash force.

10

Angular Momentum Simulator

Advanced

The spinning-skater effect: pull arms in, L = Iω spins you up.

Statics & Simple Machines

Balanced forces, and machines that trade force for distance.

11

Torque & Balance Simulator

Beginner

Balance a beam: m₁·d₁ = m₂·d₂, the moment-arm idea.

12

Buoyancy Simulator

Intermediate

Float or sink — the submerged fraction equals the density ratio.

13

Pulley Systems Simulator

Intermediate

Block-and-tackle: n rope segments cut the effort to W/n.

14

Pascal's Principle Simulator

Advanced

A hydraulic press multiplies force by the piston-area ratio.

14 interactive mechanics simulations — all free, no signup. Each pairs the governing equation with a hands-on, predict-first interaction.
