So… energy allows us to do all kinds of things. How does it get from one place to another? How does it move? Learn about energy transfer… (more…)

Over time… things fall apart. That’s entropy. Learn more about the physics of disorder… (more…)

Learn more about the waves of energy that are around you every day… light, sounds, and heat. (more…)

Kinetic energy? Potential energy? It’s all about what’s being done and what can be done! Read about kinetic and potential energy, the energy of motion… (more…)

Light waves… radio waves… microwaves… it’s all part of the electromagnetic spectrum! Learn more about these waves that are a big part of our world… (more…)

How does sound travel? In a wave… a lot like the waves you see at the beach. Waves are one of the most fascinating areas of physics! Learn more… (more…)

Light can bounce off of things (reflection), or it can be absorbed into something (absorption). Learn more about the nature of light, reflection, and absorption: (more…)

Earth has a number of systems… water, nitrogen, carbon, light, and heat all move through cycles in the Earth. Learn more about energy in Earth’s systems. (more…)

The law of conservation of energy says that energy cannot be made or destroyed. In other words, energy does not just go away. Energy can change forms. For example, light energy can become heat energy, or energy from movement can become heat energy. Energy can change, but it never goes away. Learn more about this important physical law: (more…)
