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, ...

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 ...

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 ...

Ever thought about how to eliminate confusion in multi-concept numericals and what the best way is to attempt a case study in ...

Are these machines possible without violating the laws of physics? No. A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free ...

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 ...
