Circular Motion & Gravitation notes

CBSE Class 12 Physics Unit-6: 

You need to learn the definition and types of circular motion (uniform/non-uniform)

Circular Motion

Topics like variables in a circular motion, centripetal force, centrifugal force, turning at roads, and kinematical equations in a circular motion are important.

Learn motion in a vertical circle, non-uniform horizontal circular motion, resultant acceleration and conical pendulum.

In the motion in a vertical circle, study all values of velocity at different positions given in the textbook.

Don’t miss out anything from the chapter ‘Gravitation'.

Make sure to learn Newton's law of gravitation, the constant of gravity, and its value.

From the chapter Gravitational intensity and Gravitational potential you need to study about:

- The definition and their     values – Inside the spherical shell – At a point inside the shell – At a point outside the     shell

Study the same cases for Gravitational fields due to the solid sphere.

Acceleration due to gravity & its variations and Gravitational potential energy have to be studied.

GRAVITY

 Kepler’s laws of motion - Law of orbits, law of areas, laws of periods are important too.

Don’t skip the topics from Satellites: -Orbital velocity -Time period -Energy consideration in planetary -Satellite motion -Escape velocity -Motion about the center of mass.

 Revise the notes on above mentioned topics and aim to score more.
