Im doing an isaac physics question where i need to state the symbolic equation for the GPE lost from a block sliding down a slope.
I have no number values,
The weight is W,
the angle is alpha (symbol)
the distance on the slope is l

I worked out the horizontal length to be LCos(alpha)

I cant use 9.81 because its a decimal but it tells me that my answer is wrong
(My answer being 10xWxLSin(alpha))
Help?

Gpe is mgh so WhL where h is Lsinalpaha
Think you're messing up by trying to add in gravity, but since W is the weight not mass it already includes gravity W=mg
