Okay, so I know that W=mgh=ΔUg. But, I'm a bit confused about how that relates to this equation:
W = ΔKE + ΔUg + ΔE
If you've got a block that travels vertical distance h down a frictionless incline θ you can "seemingly" use the above equation to find W, but it doesn't seem to work right.
There is no ΔE b/c there is no friction. So, you're left with:
W = ΔKE + ΔUg
From here, how do you get to W = ΔUg? There was a change in ΔKE, so I can't eliminate it!
Thanks!
