How to convert Joules(kinetic energy) plot chart into watts? Anyone know how?

• Watts are Joules per second, so area under the curve. Oct 4 '18 at 3:24
• @SolarMike But the area under the curve would give Joules times seconds, which seems a meaningless quantity. Using the slope of the curve would be better! Oct 4 '18 at 8:28
• Why you don't plot it in Watts? Solidworks does plot in Watts. Oct 4 '18 at 10:31
• @SolarMike I think you're thinking of the other way around. To get total energy from a power plot you just integrate.

• Yeah; the differential is tan( angle of the curve ) or rise rate.
