| Question | Answer |
| newtons first law of motion | Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. |
| newtons second law of motion | The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector |
| inverse square law | any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity |
| efficiency | useful work per quantity of energy |
| doppler effect | the change in frequency of a wave for an observer moving relative to the source of the wave |
| universal law of gravitation | every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them |
| newtons third law of motion | For every action there is an equal and opposite reaction. |
| big bang theory | the universe begin as a singularity not an atom that contained all the mass of the entire universe in zero space |
| Faraday's law | a changing magnetic field induces a changing electric field. the fields are both proportional& perpendicular |
| Power | is the rate at which work is performed or energy is converted |
| kirchoffs law | series- current is constant & voltage divides unevenlyparallel- voltage is current ¤t divides |
| Maxwell's law | a changing electric field induces a changing magnetic field. the fields are both proportional& perpendicular LIGHT! |
| Ohm's Law | Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere |
