A related challenge is helping students develop the graphical skills that are used At the top, gravity is acting centripetally along with the normal force, so Newtons second law gives us: N + mg = mv2/ R As h gets smaller, the speed at the top will get smaller, which will decrease the right hand side of the equation above. the curve). 5 seconds later, start the other from where the first one started.
