A general definition of physics is "the study of matter, energy and the interaction between them." Matter is the form of physical objects and space-time. Energy is a fundamental force of nature transferred between parts of a system in the production of physical change within that system and can be regarded as the capacity for doing work. Put simply, physics asks fundamental questions about the universe and attempts to answer those questions through observation and experiment.
On the website Physics Central, the American Physical Society hosts descriptions of physics experiments to perform at home, such as the creation of ice cream, a lava lamp or a compass. These can be carried out with little prior knowledge and use everyday household objects. Physics Central also publishes an "Ask a Physicist" feature for anyone with questions about how things work or why things are the way they are.Learn more about Physics
