Units in DeBrogile Equation

Postby marisaimbroane1J » Wed Oct 10, 2018 9:37 pm

Although I keep getting the correct answers for homework problems using this equation, I cannot seem to figure out how the units cancel in order to get the correct ones (eg meters or meters/sec). Can anyone explain how it works?

One joule is equivalent to other units. You can use this equation: 1J = (1kg)*(m^2)*(s^-2). Once substituting joules for these units, you can often cancel certain ones out. For example, J * s is the unit for h, but it can also be written as (1kg)*(m^2)*(s^-1) because of the multiplied s.
