Hi science shorts, regarding question 8 why is it GMm/r2 and not GMm/r

GMm/r gives potential energy - can't tell what the kinetic energy is from that.

For Q19 how do you know which one is r1 and which one is r2?

The Delta equation is the same as the gradient equation delta y divided by delta x. but in this case, gravitational potential energy(U) = - GMn/r, is a negative sign. so the original equation looks like delta U = -GMn/r (later one) - (-GMn/r)
