Physics Vocab - 2022
| Question | Answer |
|---|---|
| Force | A push or a pull that changes an objects motion |
| Mass | The amount of matter that makes up an object - how heavy an object is |
| Acceleration | When an object changes its motion in a certain direction |
| Friction | The force in the opposite direction of a moving object when two objects are in contact |
| Newtons First Law of Motion | An object will not change its motion unless a force acts on it |
| Newtons Second Law of Motion | An objects force can be calculated by multiplying its mass x acceleration. F = M x A. |
| Newtons Third Law of Motion | If one object puts a force on another object, the second object exerts a force of equal strength in the opposite direction |
| PHEOC | A template that we can use to do a scientific investigation |
| P - PHEOC | Problem - what we need to solve or investigate in the lab |
| H - PHEOC | Hypothesis - our educated guess to the answer or solution to the problem we are investigating. What we think the results are going to be |
| E/O - PHEOC | Experiment/Observation - our tests that we run to solve the problem and the data that we collect |
| C - PHEOC | Conclusion - The answer to the problem or the end result of the investigation |
| CER | Claim - Evidence - Reasoning |
| C - CER | Claim - the answer to the question |
| E - CER | Evidence - the data that we use to support our claim |
| R - CER | Reasoning - the "why" to our claim. The reason that our claim is correct |
| Kinetic Energy | The type of energy that a moving object has |
| Kinetic Energy Equation | KE = 0.5 x mass x velocity^2 |
| Potential Energy | The energy that an object stores due to its position or stress |
