The dictionary definition of physics is “the study of matter, energy, and the interaction between them”, but what that really means is that physics is about asking fundamental questions and trying to answer them by observing and experimenting.

Physicists ask really big questions like:

• How did the universe begin?
• How will the universe change in the future?
• How does the Sun keep on shining?
• What are the basic building blocks of matter?

If you think these questions are fascinating, then you’ll like physics.
