Question

When you go to an amusement park, you ride ur favorite roller coaster.When you go to an amusement park, the roller coaster moves up a hill slowly and then starts to move faster as it goes toward the boytom of the hill. where on the hill will u experience the most amount of gravitiy with earth? Why?

Answer 1

The gravitational force is given by:\[F = G\frac{mM}{r^{2}}\]
You can observe that as distance changes, the force changes by the relationship:\[F \varpropto \frac{1}{r^{2}}\]
So, as distance decreases, force increases. This means the Earth pulls harder on objects closer to it.
