Question | Answer |
---|---|
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. |
