Gravitational field

-



Gravitational field

· Newton’s law of universal gravitation ‘G’ as a universal constant
· Solar system
· Kepler’s law
· Natural and artificial satellites
· Escape velocity

By the end of this lesson, the students should be able to:

· State Newton’s law of universal gravitation

· Use Kepler's law to explain the solar system

· State the significance of satellites and their types

· Explain concepts like gravitational potential, gravitational field strength, escape velocity

· Explain the geostationary (geosynchronous satellites) communication.

· Solve simple problems on the various concept of gravitational fields
