What happens to the energy of a particle, in SHM, with time in the presence of damping forces?(a) Stays constant(b) Decreases linearly(c) Decreases exponentially(d) Decreases cubically
Correct option is (c) Decreases exponentiallyThe explanation is: Energy in presence of damping forces is given by: 1/2kA^2e^-bt/m. This shows that kinetic energy decreases exponentially with time.
