Detailed lab investigation using University of Colorado's online PHET interactive. This lab investigation leads students to discovering the mathematical relationship between force, mass and acceleration.

Conservation of Momentum is a difficult concept for students to grasp mathematically. This investigation uses University of Colorado Boulder's PHET simulation to model three types of collisions; elastic, inelastic and explosions. Students will input values for beginning masses and velocities and discover the mathematical formulas used to show the conservation of momentum.

This investigation uses the "physics classroom" coulomb's law interactive simulation. The work guides students to a systematic analysis of the effect charge and distance has on the electrostatic force between two charged particles. This activity is meant to pair with the Universal law of Gravitational investigation.

Using the "physics classroom" gravitational fields interactive students will investigate the mathematical relationship between gravitational force, mass and distance between two orbiting bodies. This activity guides students through collecting and analyzing data to find the inverse square law relationship between gravity and distance and the direct relationship between force and mass. This activity is meant to pair with the Coulomb's law investigation.
