Iis rotational inertia andω(the Greek letteromega) is angular velocity. To simplify this, you can say that an object's angular momentum is the product of its mass, velocity and distance from the point of rotation. This formula is important to understanding the consequences of the conservation ...
Why do objects stop moving if momentum is always conserved? If momentum is always conserved, why do the balls eventually stop moving? The balls eventually stop because other forces are acting on them, such as air resistance and friction which reduce the speed the objects travel at. One way ...
momentum is conserved momentum is mass * velocity Nov 3, 2010 #3 IDKPhysics101 31 0 253.5*6.9=1749.15/6.8=-257.22 i think the answer should be negative or so I am told?FAQ: Cannon at rest shot on frozen pond. what is cannon balls v after cannon recoil? What ...
(yellow doesn't show up in the graph very well). the black line is the total momentum. notice that as one object increases in momentum, the other object decreases. momentum is conserved. you could do the same thing in the y-direction or the z-direction, but i think you get the idea...
Momentum is one of the few things in nature with its own law of conservation. Conservation laws identify measurable properties of a physical system that don't change as the system moves through time. Conserved quantities in physics include charge, linear and angular momentum, and mass-energy, th...
Conservation of Momentum: Conservation of momentum is a very fundamental principle in physics. It applies to all systems which are translation-invariant, meaning the physics doesn't change if we move our coordinate system. Answer and Explanation: Because energy is conserved, the swin...
My answer to this question would be that energy is simply a quantity, like momentum, which is conserved by the laws of physics. It doesn't necessarily have, or need, any significance beyond that, although in General Relativity it does act as the source of the gravitational field. Given any...

Explain. If \vec{F} is conservative, what is the potential-energy function for it? Let U=0 when x=0 What is a pressure wave? What are laws of motion? What is magnetism? What is the momentum of light? How is friction non conservative in nature? Explain with examples. What do strong...
Here is a video. In my previous discussion of Newton's Cradle, I said that in order for this thing to work, the following must be true: Elastic collisions: the kinetic energy before and after the collision must be conserved. Conserved momentum: no external forces so that the momentum (...
