Observations and discussion Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the ...

Step 2: Kinetics (Work/energy and linear impulse/momentum) Since the only force acting on P acts through the fixed point O, there are no moments about O acting on P. Therefore, angular momentum about ...

A survey of more than 1,000 physicists finds deep disagreements in what quantum theories mean in the real world ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

When Bohr got it wrong: the impact of a little-known paper on the development of quantum theory Experimental physicist Aephraim Steinberg of the University of Toronto, Canada is equally sceptical that ...
