Learn how to perform numerical calculations using projectile motion in this physics tutorial! This video guides you step by step through solving problems involving velocity, angle, and displacement, ...

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, ...

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 ...

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 ...

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 ...

In physics, the conundrum known as the 'few-body problem,' how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
