work/energy units

[Katie Bart 1I]

On the tests/midterm, should we put energy and work in units of J or KJ?

[Hiba Alnajjar_2C]

Either should be acceptable. The problem will most likely specify whether or not your answer should be in J or kJ

[Jasmine Kim 1L]

Yeah, both are okay. Usually, you would just match the units that the problem gives or use J and scientific notation if the answer is large.

Both are probably acceptable for the final answer but we may have to convert in order to do the calculations because only certain units are compatible with certain constants or values (like heat capacity)
