Physics 1 Review

Physics 1 review

What is Matter? Something that takes up space, has mass, has inertia, has weight and has energy.
What is Energy Defined As? The ways in which some change occurs in our universe. (Heat, light, gravity, etc.)
What is A Scientific Theory? A hypothesis with testable evidence and predictions.
Which Has More Mass, the Nucleus or the Electron Cloud? The Nucleus has more mass than the electron cloud.
Which Has More Charge, the Nucleus or the Electron Cloud? The Protons and Neutrons must balance out the Electrons, so they have the same amount of charge.
Which Takes Up More Space, the Nucleus or the Electron Cloud? The Nucleus is very dense and small. The Electron Cloud, while mostly made of air, takes up more space.
What Do Each of the Variables Stand for in E=mc squared? E= energy (measured in Joules), m= mass (measured in kilograms), and c= the speed of light constant, 3 x 10 to the 8th (measured in meters per second)
What Are the Four States of Matter? Solids, Liquids, Gases, and Plasma.
What Are the 3rd and 4th Dimensions? The 3rd dimension is made up of latitude, longitude, and altitude. The fourth dimension is time.
What Are Some Examples of Forces? Gravity, Electromagnets, Strong/Weak nuclear forces (caused by interaction between the nucleus and electrons)
What Is A Force? A push or a pull.
