Which of the following best describes Friction?
- A.
A non-contact force such as gravity
- B.
Tires sliding on ice
- C.
A contact force that slows an object’s motion
- D.
All of these
Correct Answer
C. A contact force that slows an object’s motionExplanation
Friction is a contact force that slows an object's motion. When two objects are in contact and there is resistance between them, it is friction that causes this resistance and slows down the motion of the object. This can be observed in various situations, such as when tires slide on ice or when we try to slide a heavy object on a rough surface. Friction is not a non-contact force like gravity, but rather a force that occurs when two surfaces come into contact and oppose each other's motion. Therefore, the correct answer is "A contact force that slows an object's motion."Rate this question:

A pull towards the ground
- B.
A push towards the clouds
- C.
The result of two metals containing iron attached together
- D.
All of these
Correct Answer
A. A pull towards the groundExplanation
Gravity is the force that attracts objects towards each other. It is the reason why objects fall towards the ground instead of floating in the air. Therefore, the statement "A pull towards the ground" accurately describes gravity. The other options, "A push towards the clouds" and "The result of two metals containing iron attached together," are incorrect and do not accurately describe gravity.Rate this question:

Which of the following best describes non-contact forces?
- A.
Pulling & Colliding
- B.
Magnetism & Inclined Planes
- C.
Gravity & Magnetism
- D.
Pushing & Pulling
Correct Answer
C. Gravity & MagnetismExplanation
Non-contact forces refer to forces that act on objects without any physical contact between them. Gravity and magnetism are examples of non-contact forces. Gravity is the force that attracts objects towards each other, such as the force that keeps us on the ground and the force that keeps planets in orbit around the sun. Magnetism is the force exerted by magnets, which can attract or repel other magnets or magnetic materials. Both gravity and magnetism can act over a distance, without the need for direct contact between objects.Rate this question:

When you increase the distance of a moving object on an inclined plane ...
- A.
Less force is needed
- B.
More force is needed
- C.
The force remains the same
- D.
No force is needed
Correct Answer
A. Less force is neededExplanation
When you increase the distance of a moving object on an inclined plane, less force is needed. This is because as the distance increases, the inclined plane provides a longer path for the object to travel, allowing it to cover more distance with the same amount of force. This means that the force required to move the object along the inclined plane decreases as the distance increases.Rate this question:

The best definition of Work is the ability to ...
- A.
Feel exhausted and tired
- B.
Take a lunch break
- C.
Move an object
- D.
Sit idle
Correct Answer
C. Move an objectExplanation
Work is defined as the ability to move an object. This definition aligns with the scientific concept of work, which is the exertion of force on an object that results in displacement. When an object is moved, work is being done on it. The other options, such as feeling exhausted, taking a lunch break, or sitting idle, do not accurately define work in this context.Rate this question:

When two metals containing iron begin to pull closer and attach themselves, this is known as
- A.
Attract
- B.
Repel
- C.
Both A and B
- D.
Option 4
Correct Answer
A. AttractExplanation
When two metals containing iron begin to pull closer and attach themselves, it is known as attraction. This occurs due to the presence of magnetic properties in the metals, specifically iron. The magnetic fields of the two metals align and create a force that pulls them towards each other, causing them to attach. This phenomenon is commonly observed in magnets and magnetic materials.Rate this question:

More pulleys reduce the amount of force needed to lift an object.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because when multiple pulleys are used, they distribute the load over a larger number of ropes, which reduces the force required to lift the object. Each additional pulley increases the mechanical advantage, making it easier to lift heavy objects. This principle is based on the concept of leverage and the trade-off between force and distance.Rate this question:
-
- 26.
Less pulleys reduce the amount of force needed to lift an object.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because in reality, using more pulleys actually reduces the amount of force needed to lift an object. Pulleys are used to distribute the weight of the object evenly across multiple ropes, which reduces the force required to lift it. By increasing the number of pulleys, the force needed to lift the object decreases even further. Therefore, the correct answer is false.Rate this question:
-
- 27.
The weight of something is known as its
- A.
Volume
- B.
Mass
- C.
Magnetism
- D.
Gravity
Correct Answer
B. MassExplanation
The weight of an object refers to the force exerted on it due to gravity. However, mass is the measure of the amount of matter in an object, and it is often used interchangeably with weight in everyday language. Mass is a scalar quantity and is typically measured in kilograms. Therefore, the correct answer is "Mass" as it accurately represents the concept of weight.Rate this question:
