K.E is in joules(adsbygoogle = window.adsbygoogle || []).push({});

joules = 1Nm

Nm = m/s² . m

= m²/s²

therefore

k.e = 0.5mv²

m²/s² = kg . m²/s²

there is an extra kg. I dont see how

there is the same problem with GPe

GPE = m gh

m²/s² = kg . m²/s²

How can that be. The units of 0.5kgv² need to equal Nm

Thanks :)
