Kinetic energy is a scalar quantity. This means that it is independent of the direction of an object, and is only described in terms of magnitude. The equation for kinetic energy is: KE = ½ mv2 We can see from this that, when the mass (m) of an object increases, so does its ki...
How do you prove the equation of kinetic energy (KE = 1/2mv^2)? What is the kinetic energy of a 1250 kg car moving at 12.5 m/s? How much work would the engine have to do to double the car's speed? Is kinetic energy an example of a spring force?

The last term in the equation for the kinetic energy of the turbulence has been identified as the rate of dissipation of the turbulence energy per unit mass; i.e., (14)It is easy to see that always, since it is a sum of the average of squared quantities only (i.e. ). Also, ...
Energy can be generated, or lost by the atoms running around in cyclic paths for which the work done is not zero, and no equilibrium can be maintained at all. Thermal equilibrium cannot exist if the external forces on the atoms are not conservative.) Equation (40.3), known as Boltzmann's...
The quantity 12mv212mv2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. (Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the translational kinetic energy,...
