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.

Class 11 Motion In A Plane Mind Map: The motion in a plane chapter in CBSE class 11 physics deals with the motion of objects in two dimensions. The chapter covers topics like vectors and scalars, ...

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 ...

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).

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 ...

One of the many awesome things about physics is you can study it anywhere. I’ll prove it with a fun problem that involves a cart and a ball. Not just any cart, but a cart that rolls along a table and ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This helps, sort of, but as more numbers get thrown around, it can get ...
