Principal Forces Questions and Answers
- 1.
Which of these is a contact force?
- A.
Gravity
- B.
Friction
- C.
Magnetism
- D.
None of these
Correct Answer
B. FrictionExplanation
Friction is not a non-contact force because it requires direct contact between two objects in order to occur. Gravity and magnetism, on the other hand, are non-contact forces as they can act on objects without any physical contact. Therefore, the correct answer is friction.Rate this question:

_________ is a force that pulls all objects toward their center.
- A.
Gravity
- B.
Nuclear
- C.
Electric
- D.
None of these
Correct Answer
A. GravityExplanation
Gravity is a fundamental force in nature that attracts all objects towards their center. It is responsible for keeping planets in orbit around the sun, causing objects to fall towards the Earth, and governing the motion of celestial bodies in the universe. Gravity is a universal force that acts on all objects with mass and is directly proportional to the mass of the objects involved. This force is what gives weight to objects and is crucial in understanding the behavior of objects in the universe.Rate this question:

The neutral object
- A.
Has no positive and negative charges in atoms
- B.
Has less positive than negative charges in atoms
- C.
Has more positive than negative charges in atoms
- D.
Has the same positive and negative charges in atoms
Correct Answer
D. Has the same positive and negative charges in atomsExplanation
A neutral object has the same number of positive and negative charges in its atoms. This means that the positive charges from the protons in the nucleus are balanced out by the negative charges from the electrons orbiting the nucleus. As a result, the object does not have an overall positive or negative charge.Rate this question:

What is the sign of a proton?
- A.
-
- B.
+
- C.
=
- D.
X
Correct Answer
B. +Explanation
The sign of a proton is "+". This symbol is used to represent a charge that has more protons than electrons, resulting in a net positive charge. In electrical circuits, positive charges are attracted to negative charges and repel other positive charges.Rate this question:

What is the force that is usually exerted by a surface on an object resisting it?
- A.
Normal force
- B.
Gravitational force
- C.
Frictional force
- D.
None of these
Correct Answer
A. Normal forceExplanation
The force that is usually exerted by a surface on an object resisting it is called the normal force. This force is perpendicular to the surface and acts in the opposite direction to the force applied by the object. It is responsible for supporting the weight of the object and preventing it from sinking into or passing through the surface. The normal force is a contact force and is present whenever there is a surface in contact with an object. It is different from the gravitational force, which is the force exerted by the Earth on an object due to its mass, and the frictional force, which opposes the motion of an object.Rate this question:

What is the repulsive or attractive interaction that happens between any two charged bodies?
- A.
Frictional force
- B.
Magnetic force
- C.
Gravitational force
- D.
Electrical force
Correct Answer
D. Electrical forceExplanation
The repulsive or attractive interaction that happens between any two charged bodies is the electrical force. This force is caused by the attraction or repulsion of electric charges. Like charges repel each other, while opposite charges attract each other. This force is responsible for many phenomena, such as the interaction between electrons and protons in atoms, the behavior of magnets, and the functioning of electronic devices.Rate this question:

If the north and south poles of two different magnets face each other, they will
- A.
Repel
- B.
Attract
- C.
Both
- D.
None
Correct Answer
B. AttractExplanation
When the north and south poles of two different magnets face each other, they will attract each other. This is because opposite poles attract each other due to the alignment of magnetic fields. The north pole of one magnet attracts the south pole of the other magnet, creating a force of attraction between them.Rate this question:

What can magnetism do?
- A.
Attract objects
- B.
Repel objects
- C.
Both
- D.
None
Correct Answer
C. BothExplanation
Magnetism has the ability to both attract and repel objects. When two magnets with opposite poles are brought close to each other, they attract each other. On the other hand, when two magnets with like poles are brought close to each other, they repel each other. Therefore, magnetism has the power to both attract and repel objects.Rate this question:

- 9.
If the north poles of two magnets face each other, they will
- A.
Repel
- B.
Attract
- C.
Both
- D.
None
Correct Answer
A. RepelExplanation
When the north poles of two magnets face each other, they will repel each other. This is because like poles of magnets repel each other due to the magnetic field lines being in opposite directions. Therefore, the correct answer is "Repel".Rate this question:
-
- 10.
Which of these two does the magnet attract?
- A.
Gold
- B.
Silver
- C.
Both
- D.
None
Correct Answer
D. NoneExplanation
Gold and silver are not magnetic materials, so a magnet does not attract them. The correct answer is "None."Rate this question:
