Thank you for the reply. I'm wondering if there is a way to directly calculate the energy loss based on the force applied over time, rather than calculating from internal workings. The reason is we can measure the force applied over time, but measuring the internal flows is not possible.
How can I calculate the loss of potential energy when forces are applied but no motion in the system occurs? Here's an example:
Let's say I build a battery operated car that is set to drive forward, but I put it right in front of a wall. It attempts to drive forward, but instead it just pushes...
All,
Thanks for the replies. I should clarify that when I said I believe downhill running to be more "damaging," I did not mean injury or permanent damage. I just meant general muscle tearing that occurs during exercise.
Berkeman, yes, I have done a lot of trail running and still do. There is...
Hello Physics Gurus,
Please critique the following logic...
When a runner hikes/runs to the top of a mountain, the chemical potential energy inside the muscles transferred into the potential energy of the runner's body mass at the higher elevation (Pe = mass*gravity*height = mgh). Energy is...
