Khan Academy: Light and Fundamental Forces: Four Fundamental Forces

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

It's time to see the light  with a unit that focuses on light and geometric optics, including concave and convex mirrors. A variety of experiments, worksheets, and online activities are included. 

Light and electromagnetic radiation are introduced by Khan Academy. [9:37]

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

Video lecture explores what is true about how unbalanced forces relate to motion and acceleration. [6:36]

Video lesson serves as a primer on identifying balanced and unbalanced forces. [8:11]

The average American will move 12 times, which results in a lot of moving furniture! Class members consider the forces required to move objects with a creative simulation that opens with the forces required to push a filing cabinet....

Here is a nifty instructional activity on energy transfer. Physics fanatics analyze a diagram and state whether or not friction is involved. They sketch bar graphs and draw energy flow diagrams for each system as well. Circular motion,...

The mind-bending concept of space-time is further discussed by two cartoon scientists in this second of three animated films. Assign each part and the accompanying Think questions as homework or as an enrichment when working on motion...
