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, ...

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, ...

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 ...

The first part of the course includes six units, Physical World and Measurement, Kinematics, Laws of Motion, Work, Energy and ...

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 ...

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 ...

Math, specifically calculus, is a barrier to many natural sciences, technology and engineering fields. Physics, which is math-heavy, often proves similarly challenging to students who wish to pursue ...

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’ ...
