Question

what is the unit in the formula of potential energy?

Answer 1

Joule

Answer 2

how about kg-m/s2?

Answer 3

Newton ?

Answer 4

yes

Answer 5

so what about it ?

potential energy - Joule

Force - Newton

Answer 6

how about the acceleration?

Answer 7

m/s2

Answer 8

kinetic energy?

Answer 9

Joule as well

Answer 10

how to get the formula of kinetic energy?

Answer 11

energy ->\[\int\limits_{}^{}Fdx = \int\limits_{}^{}Fvdt = \int\limits_{}^{}(dp/dt)vdt = \int\limits_{}^{}vdp = \int\limits_{}^{}vd(mv) = 0.5mv^2\]

Answer 12

you can as well :

∫Fdx=∫Fvdt=∫m(dv/dt)vdt=∫vdp=∫mvdv=0.5mv2

Answer 13

assuming constant mass (not relativistic)

Answer 14

how about the formula of work and power?

Answer 15

work F dot x = Fxcos(theta)

power work/time or energy/time

Answer 16

ok :D thank u so much xD

Answer 17

if you asked about the units

so work Joule
power Joule/s but no one use it .. so : Watt
