Forces, fields & orbits — the mechanics and electromagnetism underlying the physical world.
Steer a charged beam through crossed electric and magnetic fields and find the velocity where the forces balance.
Turn a coil between magnetic poles and follow flux linkage, induced emf and load current through a generator circuit.
Spin a puck on a frictionless air table and release the tether to compare centripetal force against free-flight tangent motion.
Launch a satellite around Earth and compare circular, elliptical, impact and escape trajectories under inverse-square gravity.
Push a carriage against static and kinetic friction and separate applied force, friction and the actuator reaction.
Run a controlled hoist through a rest-to-rest lift and account for cable work, kinetic energy, power and drive loss.
