Solving Problem 1 on work and energy from an old physics final exam. Follow the step-by-step reasoning behind classic work–energy principles and see how foundational physics problems were approached ...

As a physics major, it feels like I spend the majority of my waking life solving problems. I’ve calculated the amount of water you get from mixing different ratios of steam and ice, the path of ...

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out ...

Analyze an uphill skier problem using work, energy, and power principles. See how gravitational potential energy, applied force, and friction determine the required work and power, and learn how speed ...

The image illustrates the experimental set-up: (a) Cut-away schematic of the floating sprinkler, (b) Flow control apparatus operating in suction mode, and (c) Flow imaging with a laser sheet ...
