The kinetic energy possessed by an object is the energy it possesses due to its motion. It is a quantity that depends upon both mass and speed. The equation that relates kinetic energy (KE) to mass (m) and speed (v) isKE = ½•m•v2The faster an object moves, the more ...
If an object of mass m is moving at speed v, the object's kinetic energy (KE) is given by the equation (KE) = 12 mv^2. If the mas of the object is halved and its speed is doubled, how does the kinetic energy change? ( ) A. The kinetic energy is halved. B. The kinetic ...

Some new relations are given between the kinetic and potential energies of a solitary wave. In particular, the Lagrangian is expressed as an integral involving the total energy. Alternative proofs are also given of two other exact relations satisfied by the profile of the wave. These relations ar...
