Formula for kinetic energy mass and speed
WebStrategy. (a) The known in the equation for the average kinetic energy is the temperature: – K = 1 2 m– v2 = 3 2kBT. Before substituting values into this equation, we must convert the given temperature into kelvin: T = (20.0 + 273)K = 293K. We can find the rms speed of a nitrogen molecule by using the equation. WebThe applied force converts the stored potential energy of the stationary object to kinetic energy to perform work. That’s why using the work-energy formula; we can calculate speed from force and mass. The work formula is, W= Fd. Since work done of an object is its gaining in kinetic energy KE= (1/2)mv 2. (1/2)mv 2 =Fd.
