Batteries, Resistance and Current (Giancoli CH 18)
1. Batteries are made by the difference in the electronegativity of different metals.
Electrons can flow spontaneously between metals that give off electrons easier to metals
Ray Optics PhET Lab
When you hold your glasses far away from your face, what do you see? If you look through a
magnifying glass and move it away from your face, something odd happens as you look through
the moving lens. The light tha
Compare the potential vs. current behavior of a resistor to that of a light bulb.
Determine the mathematical relationship between current, potential difference, and
resistance in a simple circuit.
The fundamental rela

Gravity Computer Activity
Use the Formula and the PhET simulation, Gravity Force Lab, F =(G*m1*m2)/d2, to
determine the Universal Gravitational Constant, G.
Fill out the chart below with data from the simulation. Calculate th
