1. The problem statement, all variables and given/known data Looking for some feedback a) Describe the energy conversions in a spring undergoing simple harmonic motion as it moves from the point of maximum compression to maximum stretch in a frictionless envoirnment. Be sure to point out the points at which there will be I) maximum speed ii) minimum speed iii) minimum acceleration 2. Relevant equations 3. The attempt at a solution When a spring is undergoing SHM energy is being conserved in the oscillating spring. This energy is being transformed between one type of energy and another. 1) At the extremes when the spring is fully stretched/compressed it has achieved the minimum speed and instantaneous velocity of 0. The reason for this is because the spring has lost its kinetic energy. When at this minimum speed it has achieved the greatest stretch Δx from its equilibrium. All the E_k at this point has been transferred over to E_e 2) At the equilibrium point or rest position of the spring the energy has all been transferred away from E_e into E_k and it has achieved the maximum speed in the system. 3) The acceleration when the spring is at the mean is minimum as well since Δx=0. Between the two extremes and the equilibrium the spring has its total energy distributed between E_e and E_k. The total energy in the system does not change during this process, it only transfers from one energy type to another.
