Seven instruments. Change a parameter, watch the identity hold. This is how an engineer learns a formula — by trying to break it.
Aim a launch, read the parabola, and hit a target using the range equation.
R = v² sin(2θ) / g
Tilt a plane, draw the free-body, and watch friction decide whether the block moves.
a = g (sin θ − μ cos θ)
Trade kinetic and potential energy in a conservative oscillator. Watch the bars.
E = ½ k A² = ½ mv² + ½ kx²
Two carts, one number that never lies: total momentum. Dial restitution from glue to elastic.
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
The namesake. Place two loads on a beam and find the pivot that puts net torque to zero.
Στ = 0
Length and g set the clock. Large angles break the small-angle story.
T = 2π √(L/g)
Ohm and Kirchhoff on a live breadboard. Series versus parallel, power in watts.
V = IR
