Explore the critical angle condition that determines the motion of a spool under applied force. This physics problem breaks down the concepts step by step, explaining when the spool rolls forward, ...

In this video, we’ll break down how to solve physics problems involving the motion of a 2D spring. Learn about the forces at play, how to model the spring’s movement, and the key concepts behind ...

The best questions are always the ones that don't have a single clear answer. In my physics classes, I like to present students with problems that can promote a lively discussion—and to do that, they ...

Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning ...

Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

MINNEAPOLIS -- In a cavernous basement laboratory at the University of Minnesota, Thomas Stoffregen thrusts another unwitting study subject -- well, me -- into the "moving room." The chamber has a ...

Here is classic (and difficult) physics problem that poses an interesting question: Take two points in space, Point 1 and Point 2. What is the path from point 1 to 2 that a frictionless object could ...
