Momentum - Mr. Shaffer at JHS
... Impulse = Change in Momentum If momentum changes – what does not have to change? A) Mass B) Velocity C) Time When things change momentum, most of the time the object is changing its Velocity, and not its mass. Think about it… while walking down the hallway, if Wanted to change your momentum, would ...

Poynting Vector and Power Flow in Electromagnetic Fields
... (W/mt ) is called the Poynting vector and it represents the power density vector associated with the electromagnetic field. The integration of the Poynting vector over any closed surface gives the net power flowing out of the surface. Equation (6.36) is referred to as Poynting theorem and it states ...
