Explain the process of mechanical energy exchange during oscillations of a pendulum. As the pendulum falls, is converted into . When the pendulum reaches the bottom of the swing, all of its energy is composed of . When the pendulum rises, is lost and is gained. At the top of the swing, all of its energy is composed of , just as at the start of the swing.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
