SUMMATIVE ASSESSMENT

 

VERY SHORT ANSWER TYPE QUESTIONS
 
1. Who gave the Universal law of gravitation
 
Ans. Issac Newton gave the universal law of gravitation.
 
2. What do you mean by gravitation ?
 
Ans. The force of attraction between any two particles in the universe is called gravitation.
 
3. State Universal law of gravitation.
 
Ans. The force of attraction between two particles or objects is (i) directly proportional to the product of the masses of the objects and (ii) inversly proportional to the square of the distance between them.
 
4. Write an expression for the gravitational force between the earth and a body on the earth.
 
Ans. F= GMm/r2 , where M is the mass of the earth, m is the mass of the body, r is the radius of the earth and G is
 
5. The distance between two particles is decreased. Will the gravitational force between them increase or decrease?
 
Ans. F ∝ 1/r2. So, gravitational force (F) increases when the distance (r) decreases.
 
6. An iron ball exerts a force F on the rubber ball. How much force, the, rubber ball will exert on the iron ball ?
 
Ans. The rubber ball also exerts the same force F on the iron ball.
 
7. Define Universal gravitational constant (G)..
 
Ans. Universal gravitational constant is defined as the force of attraction between two objects of unit masses separated by unit distance.
 
8. Write down the unit of ‘G’ in S.I.
 
Ans. Nm2 /kg2.
 
9. What is the value of ‘G’ ?
 
Ans. G= 6.673 × 10–11 Nm2/Kg2.
 
10. The value of G = 6.673 × 10–11 Nm2 kg–2 on the surface of the earth. What is the value of G on the surface of the moon ?
 
Ans. The value of G on the surface of the moon = value of G on the surface of the earth (i.e., 6.673 × 10–11 Nm2 kg–2)
 
11. The gravitational force between the earth and an object is known as ............
 
Ans. Gravity or force of gravity.
 
12. The gravitational force between two objects on the earth is 2 N. What will be the gravitational force between these two objects on the surface of the moon ?
 
Ans. Same force i.e. 2 N.
 
13. Tides in oceans are formed due to gravitational force between ...........and.............
 
Ans. the moon, the earth.
 
14. Name the force which is responsible for the revolution of planets around the sun.
 
Ans. Gravitational force of attraction between the planet and the sun. This force provides the necessary centripetal force to the planet to move in a circular orbit around the sun.
 
15. Name the force which is responsible for the revolution of moon around the earth.
 
Ans. The Gravitational force between the earth and the moon provides the centripetal force to the moon to move in a circular path around the earth.
 
16. The gravitational force between two bodies varies with r as (a) 1/r    (b) 1/r2    (c) r2 (d) r
 
Ans. (b)
 
17. Is acceleration due to gravity on the surface of moon less or more than the acceleration due to gravity on the surface of earth ?
 
Ans. Acceleration due to gravity on the surface of the moon is less than that on the surface of the earth.
 
18. Write the expression for the acceleration due to gravity.
 
g = GM/R2
 
19. What is the SI unit of acceleration due to gravity (g)
 
Ans. ms–2
 
20. What is the value of acceleration due to gravity on the surface of earth ?
 
Ans. g = 9.8 ms–2
 
21. Is acceleration due to gravity a scalar or a vector quantity ?
 
Ans. It is a vector quantity.
 
22. What is the value of acceleration due to gravity on the surface of moon ?
 
Ans. g = 1.6 ms–2 on the surface of moon.
 
23. Acceleration due to gravity on the surface of moon = ........ × Acceleration due to gravity on the surface of the earth.
 
Ans. 1/6
 
24. Where is the acceleration due to gravity more : at poles or at equator ?
 
Ans. At poles
 
25. What is the value of '9' at the centre of the earth ?
 
Ans. Zero.
 
26. What will be the direction of acceleration due to gravity if the body is thrown vertically upward ?
 
Ans. The direction of acceleration due to gravity is always towards the centre of the earth i.e. in the downward direction.
 
27. Define mass of a body.
 
Ans. Mass of a body is defined as the quantity of matter contained in the body.
 
28. Why is mass known as inertial mass ?
 
Ans. Since mass is a measure of the inertia of a body, so the mass is known as inertial mass.
 
29. What is the SI unit of mass ?
 
Ans. S.I. unit of mass is kilogram
 
30. Is mass of a body a scalar or a vector physical quantity.
 
Ans. Mass is a scalar physical quantity.
 
31. The mass of a body at the equator is 20 kg. What will be the mass of this body at the poles ?
 
Ans. 20 kg.
 
32. Define weight of a body.
 
Ans. The force with which a body is attracted by the earth is known as the weight of the body.
