Newton’s First Law |
Every object in uniform motion tends to remain in that state of motions unless external force is applied to it. |
Remain in motion |
|
|
Newton’s second law |
Force equals mass times acceleration (F=m*a) |
Force formula |
|
|
Newton’s third law |
For every action there is an equal and opposite reaction. |
Equal and opposite |
|
|
First law of thermodynamics |
Energy cannot be created nor destroyed, just converted from one form to another. Solar > Chemical > Potential > Mechanical > Kinetic > Electrical |
Converted |
|
|
Second law of thermodynamicsDcalar quantities |
No conversion is 100% efficiency. i.e. an incandescent light bulb loses 95% of its energy in the form of heat, therefore it is only 5% efficient. |
No 100% efficient |
|
|
Scalar quantities |
Quantities which describe the magnitude (size or amount) but NOT the director. (Distance, speed, mass) |
Distance |
|
|
Vector quantities |
Measurements that include magnitude and direction. (Position, displacement, velocity, and acceleration. |
Displacement |
