I have an equation relating potential energy1 plus gravitational energy1 = potential energy2 plus gravitational energy2
1/2 mv21 + mg1 = 1/2 mv22 + mg2
Now cancelling out the terms I have
v21 + 2gy1 + v22 2gy2
Now I don't understand why mg in the second term of both expressions don't cancel out. Why are we left with 2gy, not just y
