The force that opposes motion between the two objects that are in close contact is known as what?
- A.
Friction
- B.
Gravitational force
- C.
Nuclear force
- D.
Magnetic force
Correct Answer
A. FrictionExplanation
Friction is the force that opposes motion between two objects in close contact. When two surfaces rub against each other, the irregularities in their surfaces create resistance, resulting in friction. This force acts in the opposite direction to the motion and can make it difficult for objects to move or slow them down. Friction is a common phenomenon experienced in everyday life, such as when walking on the ground or when trying to slide a heavy object. It is caused by the interaction between the atoms and molecules of the two surfaces in contact.Rate this question:

The orbiting of the moon around the earth is an example of what kind of force?
- A.
Magnetic force
- B.
Contact force
- C.
Non-contact force
- D.
Frictional force
Correct Answer
C. Non-contact forceExplanation
The orbiting of the moon around the earth is an example of a non-contact force because there is no direct physical contact between the moon and the earth. Instead, it is the force of gravity that keeps the moon in its orbit. Gravity is an attractive force that acts between any two objects with mass, even when they are not in direct contact. In this case, the force of gravity between the earth and the moon is what allows the moon to continuously orbit around the earth without any physical contact between the two.Rate this question:

The types of force that are applied when the two objects are in direct contact are called what?
- A.
Magnetic force
- B.
Contact force
- C.
Non contact force
- D.
Gravitational force
Correct Answer
B. Contact forceExplanation
When two objects are in direct contact, the types of force that are applied between them are called contact forces. These forces include friction, normal force, tension, and applied force. Contact forces require physical contact between objects for them to occur. Magnetic force and gravitational force are examples of non-contact forces, as they can act on objects without direct physical contact.Rate this question:

Which of the following is an example of non-contact force?
- A.
Electrostatic Force
- B.
Gravitational Force
- C.
Magnetic Force
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Non-contact forces are forces that act on an object without physically touching it.
Electrostatic Force: This is the force between charged particles. It can attract or repel objects without any physical contact.
Gravitational Force: This is the force of attraction between two masses. It acts over a distance and does not require the objects to be in contact.
Magnetic Force: This is the force between magnetic poles or magnetic materials, which can also act over a distance.
All these forces are examples of non-contact forces as they do not require physical contact to have an effect.Rate this question:

What is the basic unit of force?
- A.
Joule (J)
- B.
Newton (N)
- C.
Watt (W)
- D.
None of the above
Correct Answer
B. Newton (N)Explanation
The basic unit of force is the Newton (N). This is because force is defined as the interaction that causes an object to accelerate or deform. The Newton is the unit used to measure this force, and it is derived from the fundamental units of mass, length, and time. The Joule (J) is the unit of energy, the Watt (W) is the unit of power, and "None of the above" is incorrect as the Newton is indeed the correct answer for the basic unit of force.Rate this question:

What type of force is applied when a body is responsible for moving another?
- A.
Gravitational force
- B.
Frictional force
- C.
Push and pull
- D.
Magnetic force
Correct Answer
C. Push and pullExplanation
When a body is responsible for moving another, the force applied can be described as a push and pull force. This type of force involves the exertion of a force in one direction to move an object, and then exerting a force in the opposite direction to bring it back. It is a common type of force that we experience in our everyday lives when we push or pull objects to move them.Rate this question:

Which of the following is an example of contact force?
- A.
Attraction
- B.
Repulsion
- C.
Nuclear force
- D.
Tension
Correct Answer
D. TensionExplanation
Tension is an example of a contact force because it occurs when an object is pulled or stretched by another object in direct contact with it. This force is transmitted through physical contact between the two objects, such as when a rope is pulled taut or a spring is stretched. Unlike attraction or repulsion, which are non-contact forces, tension requires direct physical contact between objects to occur. Nuclear force, on the other hand, is a non-contact force that acts within the nucleus of an atom, making it unrelated to tension.Rate this question:

Objects can only be affected by electrostatic force if they have what?
- A.
Mass
- B.
Frequency
- C.
Charge
- D.
Shape
Correct Answer
C. ChargeExplanation
Objects can only be affected by electrostatic force if they have charge. The electrostatic force is the force of attraction or repulsion between charged objects. Objects with no charge will not experience any electrostatic force. Mass, frequency, and shape do not directly affect the electrostatic force between objects.Rate this question:

What exactly is a force?
- A.
A push and pull
- B.
Gravity
- C.
Charge
- D.
Mass
Correct Answer
A. A push and pullExplanation
A force can be defined as a push or a pull. It is a physical interaction between two objects that causes a change in their motion or shape. When an object is pushed or pulled, a force is exerted on it, which can result in acceleration or deformation. Therefore, the answer "A push and pull" accurately describes the nature of a force.Rate this question:

What is the name of the force by which the objects return to their original state after being stretched or compressed by an external force?
- A.
Gravitational force
- B.
Tension
- C.
Elasticity / Elastic force
- D.
Magnetic force
Correct Answer
C. Elasticity / Elastic forceExplanation
Elasticity is the property of a material that allows it to return to its original shape and size after being stretched or compressed by an external force. When an object is stretched or compressed, the elastic force within the material pulls it back to its original state. This force is called elasticity or elastic force. Gravitational force is the force of attraction between two objects with mass, tension is the force exerted by a string or rope when it is pulled, and magnetic force is the force exerted by magnets.Rate this question:
