Section F: Match the Following (1 Mark Each)

1. Frictional force                                                      a) Helps objects float
2. Gravitational force                                               b) Acts between charged objects
3. Magnetic force                                                      c) Opposes motion

5. Electrostatic force                                                 e) Works between magnets

Section H: True or False (1 Mark Each)

1. Friction always reduces efficiency. (True/False)
2. Buoyant force only acts on solid objects. (True/False)

 Answers:

1. A push or pull acting on an object.
2. Moving a stationary object, changing the shape of an object.
3. Newton (N).
4. An apple falling from a tree.
5. They repel each other.

6. Frictional force
7. Earth
8. Buoyant
9. Heat
10. Attract
11. c) Destroying matter
12. b) Gravitational force
13. a) Adding grease
14. c) Interaction of electric charges
15. b) Upward
16. Frictional force resists the relative motion between two surfaces in contact. Example: Brakes on a car.
17. Magnetic force causes like poles to repel and opposite poles to attract.
18. Friction provides grip for walking and allows writing on surfaces.
19. Buoyant force acts upwards, countering the weight of an object to make it float.
20. Friction causes wear and tear, like erosion of shoe soles.
21. Force can move stationary objects (e.g., pushing a car), stop moving objects (e.g., brakes), change speed (e.g., pushing a swing), change direction (e.g., kicking a ball), or change shape (e.g., squeezing a soft ball).
22. Gravitational force pulls objects towards Earth, while magnetic force attracts or repels based on magnetic poles. Gravitational force acts on all objects; magnetic force acts on specific materials.
23. Electrostatic force occurs when objects become charged. Example: A charged comb attracting paper due to opposite charges. Like charges repel; opposite charges attract.
24. Friction allows walking and writing but also causes wear and energy loss. Its dual role makes it both essential and problematic.
25. Buoyant force pushes up against an object’s weight. Objects float if buoyant force > weight, sink if weight > buoyant force, and remain suspended if forces are equal.
26. c) Opposes motion
27. d) Pulls objects towards Earth
28. e) Works between magnets
29. a) Helps objects float
30. b) Acts between charged objects
31. True
32. False
