Lesson: Newton’s Law of Universal GravitationPhysics
In this lesson, we will learn how to identify the gravitational forces produced between objects using their masses and the universal gravitational constant.

Find the mass of the Sun. Use a value of km for the average distance between the centers of Earth and the Sun.
Evaluate the magnitude of gravitational force between two 5.0 kg mass spherical steel balls separated by a center-to-center distance of 15 cm.
Astrology makes much of the position of the planets at the moment of one’s birth. The only known force a planet exerts on Earth is gravitational.
Calculate the gravitational force exerted on a baby of mass 4.20 kg by a doctor with a mass of 100 kg if they are separated by a distance of 0.200 m.
Calculate the gravitational force exerted on a baby of mass 4.20 kg by the planet Jupiter. Use a value of kg for the mass of Jupiter and use a value of m for the separation between the planet and the baby.
