This is an animation of a Rube Goldberg contraption that incorporates energy transfers and conversions into a chain reaction. You must answer questions to proceed. Once the cat is fed, you can rerun the animation to test your understanding of how energy can travel and change.
Learn that balanced forces produce no change in the movement of an object. Check out the slideshow and then test yourself with the questions.
This animated tutorial explains what forces are and what they can do. Use the arrows below the animations to move through the slides. Take the test at the end.
In this animated video, students learn about mass: the measure of an object’s ability to resist being accelerated by a force.
