FLASHCARD QUESTION
Front
What is Hooke's Law?
Back
Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance. It can be expressed as F = kx, where F is the force applied, k is the spring constant, and x is the extension or compression of the spring.

FLASHCARD QUESTION
Front
What does the term 'extension' refer to in the context of springs?
Back
Extension refers to the additional length that a spring gains when a force is applied to it.

FLASHCARD QUESTION
Front
What is a spring constant?
Back
The spring constant (k) is a measure of a spring's stiffness. It is defined as the force required to compress or extend the spring by one unit of length.

FLASHCARD QUESTION
Front
How do you determine the stiffness of a spring?
Back
The stiffness of a spring can be determined by its spring constant. A higher spring constant indicates a stiffer spring.

FLASHCARD QUESTION
Front
What is the formula to calculate the force exerted by a spring?
Back
The formula to calculate the force exerted by a spring is F = kx, where F is the force, k is the spring constant, and x is the extension or compression.

FLASHCARD QUESTION
Front
If a spring has a spring constant of 330 N/m, how much force is needed to compress it by 0.45 m?
Back
Using F = kx, F = 330 N/m * 0.45 m = 148.5 N.

FLASHCARD QUESTION
Front
What does a high spring constant indicate about a material?
Back
A high spring constant indicates that the material is stiff and requires a large force to produce a small extension or compression.
