Momentum uncertainty equation

WebIn equation form, linear momentum p is. p = m v. You can see from the equation that momentum is directly proportional to the object’s mass ( m) and velocity ( v ). Therefore, the greater an object’s mass or the greater … WebLight has no rest mass, but it does have momentum and energy. Using Einstein's full equation, E² = p²c² + m²c⁴, with a m (rest mass) = 0, we see that for light, E = pc. So, …
