How can I relate linear and angular motion using a single formula? [closed]
I want to relate linear and angular motion using a single formula.
Assume I have a 10m rod, and I apply a force of 5N on it, 2.5m away from the
axis of rotation for 1s. How can I determine the r …

If velocity is constant, how can $p = F\cdot v$ be non zero?
The plane itself is exerting some force in order to overcome the effects of gravity.
Consider that if you turn off the engine, the plane would go crashing down. The only reason you are able to obser …
