Physical science is the study of matter and energy. It has two main branches - chemistry, which looks at the structure and properties of matter and how substances change through chemical reactions, and physics, which studies different forms of energy and concepts like motion, force, and gravity. Both matter and energy are fundamental to physical science - matter is what everything is made of, while energy is the ability for matter to do work and is present in all objects and substances.

1. Exploring Physical Science Chapter 1, Section 1

2. Science A process of gathering knowledge about the natural world.

3. What is Physical Science? The study of matter and energy. Matter is the “stuff” that everything is made of. Shoes, pencil, air Energy is the ability to do work. NRG is partly responsible for rainbows, but is not the rainbow itself. All moving objects and non-moving objects have energy. Food has NRG that is xferred to you.

5. Chemistry Looks at the structure and properties of matter. Different substances behave differently under the same conditions. Chemistry is also the study of how substances change. Chemical reaction takes place when one substance reacts w/ another substance to make a new substance.

6. Physics Studying different forms of NRG is what Physics is all about. Motion, force, gravity, electricity, light, and heat are parts of physics. Riding a bike and using your brakes Force causes motion

7. Which of the following statements is true? NRG is the ability to do work. Air is made of matter. All matter has NRG. All of the above.

8. What is the difference between Chemistry & Physics?

9. Answer: Chemistry is mainly the study of the properties and interactions of matter. Physics is mainly the study of forces and motion.
