Energy and Heat

The ability to do work is called

• velocity
• energy
• conversion
• friction.

The total potential and kinetic energy of the particles in an object is called

• mechanical energy
• thermal energy
• chemical energy
• electrical energy

An example of something that stores chemical energy is

• lightning
• a microwave
• a match
• light

Moving water can be used to produce electricity because

• most forms of energy can be converted into other forms
• energy cannot be converted into other forms of energy
• potential energy can be converted into kinetic energy, but not vice versa
• kinetic energy can be converted into potential energy, but not vice versa
