A mass attached to a spring and lying on a table is pulled and released, causing the mass to oscillate in periodic motion. If losses due to friction and air resistance can be ignored, what types of energy conversions are involved in this system?
a) Energy is converted between kinetic and gravitational potential energy.
b) Energy is converted between kinetic and elastic potential energy.
c) Energy is converted between thermal and elastic potential energy.
d) Energy is converted between kinetic and chemical potential energy.
