Given the Earth orbits the Sun at a distance of 1.49*10^11m with Me = 5.97*10^24kg and Msolar = 1.99*10^30, what is the gravitational force between the Earth and Sun?

Using F = Gm1m2/r^2 and substituting in the values, we get F = 3.57*10^22N.

Show that the orbital period of a satellite is given by T^2=(4pi^2r^3)/(GM) where r is the orbital radius, G is the gravitational constant and M is the mass of the Earth. Then find the orbital radius of a geostationary satellite.


why is gravitational potential negative?


A pendulum of mass m is released from height h with a speed v at the bottom of its swing. a) What is the gravitational potential energy at height h and the kinetic energy at the bottom of its swing? b) Use conservation of energy to define the speed v.


"An inclined plane at an angle of 25 degrees to the horizontal has a pulley at its top. A 30kg block on the plane is connected to a freely hanging 20kg block by means of a cord passing over the pulley. From rest how far will the 20kg block fall in 2s?
