Hooke's Law Quiz

What is the formula for Hooke's law?

• F = kx

• F = k^2

• F = mx

• F = k/x

What is the unit of spring constant?

• N/kg

• m/s

• kg/m

• N/m

What happens to the spring constant when the stiffness of a spring increases?

• Increases

• Decreases

• Remains the same

• Becomes negative

What is the relationship between force and extension in Hooke's law?

• Inverse proportional

• No relationship

• Directly proportional

• Exponential relationship

What is the elastic limit in the context of Hooke's law?

• The minimum stress a material can withstand

• Maximum stress or force that a material can withstand without permanent deformation

• The amount of force needed to stretch a material

• The point at which a material breaks completely

Give an example of an application of Hooke's law in everyday life.

• Using a spring scale to measure weight

• Using a ruler to measure length

• Using a thermometer to measure temperature

• Using a calculator to solve math problems

How does Hooke's law apply to the behavior of rubber bands?

• The force needed to extend a rubber band is not related to the distance it is stretched.

• Rubber bands do not follow Hooke's law.

• The force needed to extend a rubber band is inversely proportional to the distance it is stretched.

• The force needed to extend or compress a rubber band is proportional to the distance it is stretched or compressed.

What is the significance of the slope of a force vs. extension graph in Hooke's law?

• It represents the spring constant (k) of the material.

• It represents the temperature of the material.

• It indicates the weight of the material.

• It shows the color of the material.

Explain the concept of restoring force in the context of Hooke's law.

• The restoring force is the force that only acts when the object is at rest.

• The restoring force is the force that acts to bring an object back to its original position after it has been displaced.

• The restoring force is the force that has no effect on the object's position after displacement.

• The restoring force is the force that causes an object to move further away from its original position.

What are the factors that can affect the accuracy of Hooke's law in real-life applications?

• Color, shape, and size

• Volume, density, and pressure

• Time, distance, and speed

• Material properties, temperature, and stress levels
