This video is goated with the sauce thank you so much mr shorts. 👍😎
absolute legend saving my exams rn
for 8:47 why did you multiply the force with the r? isn’t it supposed to be inversely proportional so you’re supposed to do F1 x 1/r^2 = F2 x 1/r^2
They are inversely proportional, so multiplying them gives a constant.Watch my proportionality video.
@ thanks!
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)
