—Period (s)
—Angle (°)
—Velocity (m/s)
—KE (J)
Simple Pendulum · Period: T = 2π√(L/g) · Restoring force: F = –mg·sin(θ) · Adjust length and gravity to see how they affect oscillation period.
—Beat Freq (Hz)
—Mode
Wave 1
Wave 2
Superposition
Wave Interference · When two waves meet, they superpose. Constructive interference adds amplitudes; destructive cancels them. Beat frequency = |f₁ - f₂|.
—Radius (AU)
—Speed
—Grav Force
—Orbit Type
Gravitational Orbits · F = G·M·m/r² · Kepler's third law: T² ∝ a³ · Increase velocity past escape velocity to see hyperbolic trajectories.
—p Before
—p After
—KE Before (J)
—KE After (J)
Collisions · Elastic (e=1): KE conserved · Perfectly Inelastic (e=0): objects stick · Momentum always conserved: m₁v₁ + m₂v₂ = const.

—Force (N)
—Distance
—Interaction
Electric Field · Coulomb's Law: F = k·q₁·q₂/r² · Field lines point away from (+) toward (−) · Equipotential surfaces are perpendicular to field lines. Drag charges around!
