Solve the classic blob jump physics problem using the Work–Energy Theorem. Follow how gravitational potential energy, kinetic energy, and energy transfer explain the launch speed and maximum height, ...

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, ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

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 ...

Shini Somara introduces us to the ideas of motion in a straight line. In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight ...

Neil Downie believes that supporting students to devise, build and test their own projects can help to get them and their teachers interested in and enjoying physics Practical solutions Students who ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...
