I may have misinterpreted this but today in calculus (AB) we were forming solids from 2 dimensional equations. One of the methods involved taking an integral of an area equation to solve for a solids volume. I got very excited as I often have difficulty remembering volume equations but am...
2 semi-related questions:
1)If momentum is conserved in a system of 2 objects colliding and we are aware of their masses and initial velocities, let's say object 1 is moving at a certain velocity towards object 2 at rest, is there any way to solve for their final velocities without knowing one...
I've heard of the muons and electrons that constantly hit Earth's surface in cosmic rays coming from extra terrestrial particles that break up in Earth's atmosphere but I was curious what factors played a role in the type of radiation produced from these particles in the atmosphere (i.e. More...
So I've been thinking about the Von Braun rotating space station model lately and I was curious about a few things. First, if someone dropped a ball in one (the ship is spinning so the centripetal force is equal to the persons weight on Earth so it creates an artificial acceleration of gravity...
Are photons massless? They have energy and can be affected by gravity, so don't they have mass? I've heard plenty of people say that photons are massless, does this just mean that they have negligible mass?
Also, if only light/photons can move at the speed of light, then wouldn't everything be...
*the sum of all the forces in a full system are zero.
If the sum of forces on every object was zero, nothing would move because everything would be in equilibrium
Both forces in a force pair described in Newton's third law exist but are not both acting on the same object, otherwise objects would all be in equilibrium. The force of tension on an object from a rope has a force of an equal magnitude on the other end of the rope.
A good example of force...
