Jun 10, 2023 · Question 1: What are the differences between the mass of an object and its weight? Answer: Mass is the quantity of matter contained in the body. Weight is the force of gravity acting on the body. II. It is the measure of inertia of the body. It is the measure of gravity. III. Mass is a constant quantity. Weight is not a constant quantity.
Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth. Solution: Consider F as the force of attraction between an object on the surface of earth and the earth. Also, consider ‘m’ as the mass of the object on the surface of earth and ‘M’ as the mass of earth.
May 30, 2021 · Gravitational force between the earth and an object is known as the weight of the object. 10. Amit buys few grams of gold at the poles as per the instruction of one of his friends.
- How does the force of gravitation between two objects change when the distance between them is reduced to half? Answer. We know, F = G m1m2d2\dfrac{\text{m}_1\text{m}_2}{\text{d}^2}d2m1m2
- Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object? Answer.
- What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6 × 1024 kg and radius of the earth is 6.4 × 106 m.)
- The earth and the moon are attracted to each other by gravitational force. Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth?

Jul 3, 2020 · Why is the weight of an object on the moon its weight on the earth? Solution: The weight of an object depends on the value of acceleration due to’gravity g. The value of g on earth is 6 times more than that of moon because, the mass and radius of the earth is more than the mass and radius of the moon. Weight of a body of mass m on moon is ...

So, we know that mass of earth is larger as compared to objects placed on it. Therefore, acceleration is produced in earth but the magnitude is very small (almost nil) that we hardly see it moving. a) It holds the atmosphere in place. b) It keeps planets & sun, satellites in their objects. c) It helps in the formation of tides.
