... Historical Note: Mass-Energy Equivalence Einstein imagined a closed and isolated box with a light bulb at one end and a detector at the other. Once the bulb emits a flash of light toward the detector, the box recoils, because wave carries momentum. When the flash is received by the detector, the bo ...

... The diagram below represents how water is funnelled into a pipe and directed to aturbine at a hydro3 electric power plant. The force of the falling water rotates theturbine. Each second, 200 m of water is funnelled down a vertical shaft to the turbine below. The vertical height through which the wat ...

Relative Motion in Two Dimensions
... Reason: We know that the centripetal acceleration always points toward the center of the circle. Its magnitude is equal to the square of the speed divided by the radius of motion. That is, ac = v2/r. To measure the speed of an object moving in a circle, we measure the period, T, the time needed for ...
