WebThe quantity 1 2 mv 2 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, KE = 1 2 mv 2, 7.12. 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. WebTwo objects that have equal masses head toward one another at equal speeds and then stick together. Their total internal kinetic energy is initially 1 2 mv 2 + 1 2 mv 2 = mv 2. The two objects come to rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision. fortigate 100f firmware
