Mechanical energy is made when something is moved. The energy that is moving is kinetic. And potential energy is stored energy. Mechanical energy can be used to store energy and to cause moving energy. For instance: a slingshot. Pulling back the band creates potential energy and releasing it creates kinetic energy.
D) The speed of a wave slows as it travels at different speed in different media.
One cubic centimeter and one milliliter are equal volumes.
