Which of the following materials obeys Hooke's law?
- A.
Rubber
- B.
Steel
- C.
Glass
- D.
Plastic
Correct Answer
B. SteelExplanation
Among the options provided, steel is a material that generally obeys Hooke's Law within its elastic limit. Hooke's Law describes the linear relationship between force and displacement for elastic materials, and steel is often considered an elastic material within certain limits. It's important to note that materials like rubber, glass, and plastic may exhibit nonlinear behavior, especially under larger deformations, and may not strictly follow Hooke's Law in the same way that elastic materials like steel do. The behavior of a material under stress and strain depends on its mechanical properties and the conditions of deformation.Rate this question:

What happens to the spring constant when a stiffer spring is used?
- A.
It decreases.
- B.
It remains the same.
- C.
It increases.
- D.
None of the above
Correct Answer
C. It increases.Explanation
When a stiffer spring is used, the spring constant 'k' increases. The spring constant is a measure of the stiffness of a spring, and it quantifies how much force is needed to produce a certain amount of displacement in the spring. A higher spring constant indicates a stiffer spring, meaning it requires more force to produce the same amount of displacement compared to a less stiff spring. Therefore, the correct answer is "It increases."Rate this question:

What is the SI unit of the spring constant?
- A.
Newton (N)
- B.
Meter (m)
- C.
Kilogram (kg)
- D.
Newton per meter (N/m)
Correct Answer
D. Newton per meter (N/m)Explanation
The SI unit of the spring constant 'k' is Newton per meter (N/m). The spring constant is a measure of the stiffness of a spring and is defined as the force required to produce a unit displacement in the spring. Therefore, its unit is expressed in newtons per meter, indicating the amount of force needed to cause a one-meter displacement in the spring.Rate this question:

What happens to the displacement of a spring when no force is applied?
- A.
It remains constant.
- B.
It decreases.
- C.
It increases.
- D.
It depends on the elasticity of the spring material.
Correct Answer
A. It remains constant.Explanation
When no force is applied to a spring, and the system is in equilibrium, the displacement of the spring remains constant. In this state, the spring experiences no net force pulling or pushing it away from its equilibrium position. According to Hooke's Law, the force exerted by the spring is proportional to the displacement from its equilibrium position, so when there is no external force, the displacement does not change. Therefore, the correct answer is: It remains constant.Rate this question:

How is the spring constant determined experimentally?
- A.
By measuring the mass of the spring
- B.
By measuring the displacement of the spring
- C.
By measuring the force applied to the spring
- D.
By measuring the temperature of the spring
Correct Answer
C. By measuring the force applied to the springExplanation
In an experimental setup, the force applied to the spring is measured using a force sensor, and the resulting displacement of the spring is recorded. By plotting a graph of force against displacement and determining the slope of the linear region, the spring constant can be calculated. This process allows researchers and scientists to quantify the stiffness of the spring and understand its behavior under applied forces.Rate this question:

- A.
Plastic deformation
- B.
Elastic deformation
- C.
Fracture deformation
- D.
Viscous deformation
Correct Answer
B. Elastic deformationExplanation
Hooke's Law specifically applies to elastic deformation. Elastic deformation refers to the temporary change in shape of a material when subjected to stress, and it returns to its original shape and size once the stress is removed. Hooke's Law mathematically describes this elastic behavior, stating that the force required to deform an elastic material is proportional to the displacement from its equilibrium position.Therefore, the correct answer is: Elastic deformation.Rate this question:

What is the relationship between the spring constant and the stiffness of a spring?
- A.
They are unrelated
- B.
Higher spring constant means higher stiffness
- C.
Higher spring constant means lower stiffness
- D.
There is an inverse relationship between the two
Correct Answer
B. Higher spring constant means higher stiffnessExplanation
The relationship between the spring constant k and the stiffness of a spring is such that a higher spring constant corresponds to a higher stiffness. The spring constant quantifies the stiffness of a spring, indicating how much force is required to produce a unit displacement. A higher spring constant implies that more force is needed to achieve the same displacement, signifying greater stiffness.Therefore, the correct statement is: Higher spring constant means higher stiffness.Rate this question:

What happens to the potential energy of a spring as it is stretched?
- A.
It remains constant.
- B.
It increases.
- C.
It decreases.
- D.
It depends on the applied force.
Correct Answer
B. It increases.Explanation
When a spring is stretched, its potential energy increases. This is because the potential energy stored in the spring is directly linked to how much it has been stretched from its normal position. The more you stretch the spring, the more potential energy it gains. This increase in potential energy happens because you're doing work to deform the spring against its restoring force. So, when you stretch a spring, you're essentially storing more energy in it.Rate this question:
