Physics is the study of the world around us. What is Physics? Physics is the study of the world around us. It is the study of MATTER and ENERGY and its interaction (motion) with each other.

Physics is involved in everything around us. What is Physics? Physics is involved in everything around us.

What is Physics? This semester, we will be studying force and motion, natural laws of the universe, and energy

What is Physics? Why do things move the way they move? Laws of Motion Universal Law of Gravity Law of Conservation of Energy Law of Conservation of Momentum .

Why is Physics important? So why is Physics important? Physics is fundamental. Principles of Physics are use in Chemistry and Biology. Physics teaches us to investigate the world around us. Physics helps us appreciate our world. Physics is the basis or the reason for much of our technology. .
