Physics and Mechanics
Push objects with Newton’s laws, launch projectiles, swing pendulums, overlap waves, wire up circuits, slide blocks down slopes, spin wheels, collide pucks, float objects and bend light — with live measurements for every variable.
Topics in Physics and Mechanics
Projectile Motion
Change launch angle, speed and gravity and predict where the projectile will land.
~15 min
Pendulum Motion
Adjust length, mass and starting angle and measure the period of oscillation.
~15 min
Wave Interference
Overlap two waves and control frequency, amplitude and phase to see interference patterns.
~15 min
Electricity and Circuits
Build series and parallel circuits and measure voltage, current and resistance.
~15 min
Inclined Planes and Friction
Tilt a slope, drag a block onto it and watch static friction hold it or kinetic friction slow its slide.
~15 min
Rotational Motion, Torque and Angular Momentum
Push a wheel at different distances and angles, compare disks, rings and rods, and spin on a stool to see angular momentum conserved.
~20 min
Momentum and Collisions
Aim two pucks on an air table and compare elastic, inelastic and sticky collisions: momentum is always conserved, kinetic energy is not.
~15 min
Fluid Mechanics, Pressure and Buoyancy
Drop objects into a tank, change the fluid, and measure pressure with depth to see why things float, sink or hover.
~15 min
Geometric Optics: Reflection, Refraction and Lenses
Aim a laser at mirrors and glass, test Snell’s law and total internal reflection, and form real and virtual images with lenses.
