WebExpert Answer. True The law of conservation of energy states that energy can neither be created …. Question 6 1 pts Does Conservation also include rest energy? True False. WebRest Energy. Rest energy is given by: E0 = mc2. Einstein articulated this famous mass energy equation which for the first time exposed that the mass of an object at rest is related to its energy. For instance, the rest mass of an object increases if some energy is stored in it. This also suggests that to release energy, mass can be destroyed.

WebThe final kinetic energy is the same as the work done as long as the initial velocity is 0m/s. To get a more general answer, we can substitute the expression for the final velocity (√ (v0²+2aΔx)) into the kinetic energy equation Ek=½mv² to get Ek=½m√ (v0²+2aΔx)². This simplifies to get Ek=½m (v0²+2aΔx) WebThe kinetic energy of the spring is equal to its elastic potential energy, i.e. 1/2mv^2 = 1/2kx^2 when the spring is stretched some distance x from the equilibrium point and when its mass also has some velocity, v, with which it is moving. This occurs somewhere in between the equilibrium point and the extreme point (extreme point is when x ... cytonics reddit
