How Physics Powers Your World

From smartphones to skateboards, physics is everywhere! Understanding the principles of matter, energy, and forces helps engineers invent and improve our favorite gadgets.

Examples of Physics in Action

  • Smartphones: Use electromagnetic waves to make calls and send texts.
  • Cars: Rely on mechanics and thermodynamics to move safely and efficiently.
  • Appliances: Use electricity and magnetism to cook, clean, and cool.

Why It Matters

Knowing physics helps you understand how things work, solve problems, and even invent new devices!

Examples

  • A microwave heats food using electromagnetic waves.

  • Electric fans use motors that convert electricity into motion.
