Part A: Introduction (01:48)

FREE PREVIEW

Energy is what allows things to change in some way. Energy forms include light, electrical, chemical, sound, heat, nuclear, elastic potential, gravitational potential, and kinetic. This program will look at situations where energy transforms from one form to another.

Part B: The Many Different Forms of Energy (06:38)

Anything that moves has kinetic energy. Energy comes from fuels used; all fuels have chemical energy. Food contains essential nutrients; carbohydrates, fats, and oils contain chemical energy. Learn about carbohydrate types, milling, and digestion.

Light Energy (01:03)

Fire, screens, light bulbs and the sun produce light energy, which can make things change. Learn about the process of light and chemicals producing eyesight.

Electrical Energy (00:51)

Atoms include nuclei and electrons. They move between atoms when a battery is connected to a light bulb.

Heat Energy (00:31)

Heat energy transfers from a hot object to a cold object. It is important in cooking, maintaining body temperature at 37 degrees Celsius, and in industrial processes.

Sound Energy (01:45)

Sound is caused by vibrations and sound waves. View vocal cords and speakers in action. Sound energy produced by loud things is relatively small, but can damage our sensitive ears.

Elastic Potential Energy (01:10)

Elastic potential energy produces kinetic energy in springs and bows; see examples.

Gravitational Potential Energy (01:18)

Gravitational potential energy is stored in something lifted to higher elevations. When allowed to fall or roll downhill, it transforms to kinetic energy.

Nuclear Energy (01:51)

Nuclear energy is stored inside atomic nuclei and can be released in heat, light, and kinetic energy forms. Nuclear power plants use uranium and plutonium for steady heat to produce electricity.

Part C: Energy Transformations (10:28)

Hear the First Law of Thermodynamics. Light bulbs transform electrical energy to light energy. Animals convert chemical energy from food into kinetic and heat energy. Photosynthesis produces carbohydrates from carbon dioxide and water. Learn about solar panels, generators, wind turbines, and car engines.

Forms of Energy Summary (00:46)

Energy comes in kinetic, chemical, light, electrical, heat, sound, elastic potential, gravitational potential, and nuclear forms. It can transfer between objects and transform between forms. It can also be measured in joules.
