Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

We stop by a food truck to investigate three different ways to graph motion. Unit 2 Segment D: Graphing Motion We stop by a food truck to investigate three different ways to graph motion: position ...

Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...

Vernier Video Physics uses video data to calculate velocity over time. Vernier Software & Technology has rolled out a new application that works with the iPod touch, iPad, or iPhone to collect physics ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m 2).

This week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion. Crash Course Physics is available to ...
