Hi, I'm basically trying to figure out if there's a quick way to approximate the flight time of something thrown downwards off a cliff.
If you throw a projectile off a cliff with height H > 0 above the ground, there are 3 cases:
v_y > 0
v_y = 0 (thrown horizontally off the cliff)
v_y <...
Hi, I'm learning about momentum and kinetic energy and I wanted to know if the following relationships are true. I think they are true, but I am not sure:
If kinetic energy goes down and mass stays constant, momentum goes down
If kinetic energy stays constant and mass goes down, momentum...
I'm a physics noob but this is something I was thinking about when I read in my textbook that fluids are generally incompressible.
Let's say I had 1000 L of water enclosed in a sphere several meters thick (say, 2 meters thick) made of an extremely hard, dense metal with 0 outlets or holes of...
Sorry if the formulation is imprecise, I'm a biology major trying to study some physics. The question is:
So far, my reasoning is:
I make an assumption in Step (2) that decreasing the pressure will decrease the temperature. But I'm not sure what the justification is. I only know of the ideal...
