| 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
🗑
|
||||
| newtons third law of motion | For every action there is an equal and opposite reaction.
🗑
|
||||
| efficiency | useful work per quantity of energy
🗑
|
||||
| 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
🗑
|
||||
| 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!
🗑
|
||||
| Faraday's law | a changing magnetic field induces a changing electric field. the fields are both proportional& perpendicular
🗑
|
||||
| big bang theory | the universe begin as a singularity not an atom that contained all the mass of the entire universe in zero space
🗑
|
||||
| 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
🗑
|
||||
| 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
🗑
|
||||
| doppler effect | the change in frequency of a wave for an observer moving relative to the source of the wave
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
