Further Mechanics, Fields & Particles

Constant-speed circular motion still has centripetal acceleration.

In SHM, displacement, velocity, acceleration are sinusoidal, 90° out of phase.

Force between two masses ∝ product of masses, inverse square of distance.

Stored energy between two masses — zero at infinity, negative at finite separation.

Speed at which gravity exactly provides the centripetal force.

Force per unit positive test charge around a source charge.

Work per unit charge to bring a charge from infinity; equipotentials.

Charge stored per unit voltage; geometry sets the value.

Combination rules for capacitor networks.

Lorentz force F = qv × B and the resulting circular trajectory.

Force on a current segment and torque on a current loop.

Standard model building blocks — quarks, leptons, antimatter, and hadron classification.

Exponential decay; T₁/₂ = ln2/λ; activity A = λN.
