NCERT Solutions for Class 11 Physics Chapter 8: Important Topics

Students must have observed that all material objects tend to get attracted to the earth. If we throw something up in the sky, it comes down and falls on the ground. It was the Italian Physicist Galileo who discovered the phenomenon that all the bodies fall back on the earth with a constant acceleration. Students will get a brief description of the same and related concepts in this chapter.

The important topics in this chapter include Kepler’s Law and the Universal Law of Gravitation. Apart from these, escape velocity, gravitational potential energy, and satellites are also some important topics. Embibe covers all these topics in its NCERT Solutions for free. Furthermore, the 3D videos, Embibe Explainers, and NCERT Exemplars are also available for free at Embibe.

Now, let us look at the important topics explained by Embibe:

NCERT Solutions for Class 11 Physics Chapter 8: Points to Remember

Some of the important points to remember from this chapter are as follows:

  • The gravitational constant experiment was first done by an English scientist Henry Cavendish. Its value is 6.67408 × 10-11 m3 kg-1 s-2.
  •  Value of g on earth (at sea level) = 9.8m/s2.
  • Acceleration due to Gravity of the Earth: It is the acceleration that an object gains due to the gravitational force. Its unit is m/s2 and is represented by ‘g’.
  • Escape velocity of an object, ve=  √2GM / R =√2gR = √8πp GR2 / 3. Escape velocity at earth is 11.2 km/s.
  • Binding energy of the satellite mass ‘m’ is given by: B.E = + GMm / 2r.
  • Gravitational field strength: E = F/M.
