Faraday's Law of Induction
A voltage is induced in a coil swinging through a magnetic field. Faraday's Law and Lenz' Law are examined and the energy dissipated in a load resistor...
Electrostatic Charges
The purpose of part A of this activity is to compare and contrast the results of three different methods of charging: 1) rubbing two objects together;...
Electrical Equivalent of Heat
The purpose of this experiment is to determine the amount of electrical energy that is equivalent to a certain amount of thermal energy. This is accomplished...
Earth's Magnetic Field
The magnitude and direction of the Earth's magnetic field are measured using a Magnetic Field Sensor mounted on a Rotary Motion Sensor. The Magnetic Field...
Driven Damped Harmonic Oscillations
The oscillator consists of an aluminum disk with a pulley that has a string wrapped around it to two springs. The angular positions and velocities of the...
Driven Damped Cart Oscillations
The oscillator consists of a Smart Cart attached to two springs. The damping is provided by magnets mounted on the Smart Cart that cause eddy currents...
Conservation of Momentum
Elastic and inelastic collisions are performed with two dynamics carts of different masses. Magnetic bumpers are used in the elastic collision and Velcro®...
Conservation of Energy II
The student observes a falling object and compares its kinetic and gravitational potential and total energies as it falls. The student also demonstrates...
Conservation of Angular Momentum
A non-rotating ring is dropped onto a rotating disk. The angular speed is measured immediately before the drop and after the ring stops sliding on the...
Charge of an Electron
This is Millikan's experiment to determine the charge of an electron. The electric charge carried by an oil drop is calculated by measuring the force experienced...
