Momentum of Light in a Dielectric Medium
... Einstein postulated that a photon of radiation of frequency has an energy ប, and, based on the formula E = pc noted earlier, one might think that he would also have postulated a photon momentum p = ប / c. But neither Einstein nor anyone else associated this momentum with a photon until 1916; Pai ...

Rotational Motion of Solid Objects
... the torques produced by weights on either side of the fulcrum of our balance are equal in magnitude, the scale is balanced. It will not rotate. Most of us have tried to turn a nut with a wrench at some time. We exert the force at the end of the wrench, in a direction perpendicular to the handle (fig ...

6. The Impulse-Momentum Change Theorem
... First, observe that the answers in the table above reveal that the third and fourth columns are always equal; that is, the impulse is always equal to the momentum change. Observe also that the if any two of the first three columns are known, then the remaining column can be computed. This is true be ...

8 Linear Momentum and Collisions
... The importance of momentum, unlike the importance of energy, was recognized early in the development of classical physics. Momentum was deemed so important that it was called the “quantity of motion.” Newton actually stated his second law of motion in terms of momentum: The net external force equals ...
