What do you mean by a chronometer? What units are used for Newton's? The American physical chemist Gilbert Newton Lewis (1875 - 1946) proposed a unit of time called the "jiffy". According to Lewis, 1 jiffy = the time it takes light to travel one centimeter. ( ...
What does net force mean? Is speed a vector quantity? How many fundamental forces are there? Why is displacement a vector quantity? What two quantities are necessary for a vector quantity? How do you determine the force on an object if there are multiple forces acting on it?
Quantity A fundamental, generic term used when referring to the measurement (count, amount) of a scalar, vector, number of items or to some other way of denominating the value of a collection or group of items. You have to choose between quantity and quality. Unit (sciences) A standard ...
but what do you mean by "you can't boost a photon"? I mean that you can't change the velocity of a photon. If you transform to a boosted coordinate system, you still have a photon traveling at speed c. Boosting, as an operation on massive particles, is both ...
