In this chapter, students learn about Gravitation and the Universal Law of Gravitation, along with the Gravitation force and its importance. Later, the concepts of free fall, the value of g, and the motion of objects under the influence of the earth’s gravitational force are also discussed. Students will also get to know the differences between mass and weight and how to calculate an object’s weight on the Moon. This chapter consists of many numerical problems that must be understood and practised diligently.

Ans: The universal law of gravitation states that every object in the universe attracts every other object with force called gravitation
nal force. The force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
Ans: When an object falls freely from a certain height towards the earth’s surface, its velocity changes. This velocity change produces acceleration in the object, known as acceleration due to gravity, represented by the letter g.
The gravity-based acceleration value is,
Ans: The moon’s mass is 1/100 times and 1/4 times the earth’s radius. As a result, when compared to earth, the gravitational attraction on the moon is about one-sixth. Thus, an object’s weight on the moon is 1/6th its earth weight.
Ans: The upward force possessed by a liquid on an object that’s immersed in it is referred to as buoyancy.
Ans: The bag of cotton is heavier than the bar of iron. The cotton bag has a larger air thrust than the iron bar. The weighing machine, therefore, indicates a smaller cotton bag weight than its actual weight.
