Hooke's Law

Front

What does Hooke's Law state?

Back

Hooke's Law states that the force (F) applied to a spring is directly proportional to the extension (x) of the spring, represented by the formula F = kx, where k is the spring constant.

Front

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

Back

The elastic limit is the maximum extent to which a material can be stretched or compressed without permanently deforming. Beyond this point, Hooke's Law no longer applies.

Front

Convert 5,000 g to kg.

Back

5,000 g = 5 kg.

Front

How do you determine the stiffness of a spring?

Back

The stiffness of a spring is determined by its spring constant (k). A higher spring constant indicates a stiffer spring.

Front

Which spring is the stiffest? A spring that requires a force of 2000 N to compress it by 6.8 m, a spring that requires a force of 4000 N to stretch it by 9.0 m, a spring that requires a force of 8000 N to compress it by 45 m, or a spring that requires a force of 4800 N to stretch it by 14 m?

Back

The stiffest spring is the one that requires a force of 4000 N to stretch it by 9.0 m.

Front

What is the spring constant (k)?

Back

The spring constant (k) is a measure of a spring's stiffness, defined as the ratio of the force applied to the extension produced.

Front

If a spring has a high spring constant, what does that indicate about its material?

Back

A high spring constant indicates that the material of the spring is stiff and requires a large force to produce a small extension.

Front

What happens to a spring when it exceeds its elastic limit?

Back

When a spring exceeds its elastic limit, it will not return to its original shape and will undergo permanent deformation.

Front

What is the formula for calculating force using Hooke's Law?

Back

The formula for calculating force using Hooke's Law is F = kx.

Front

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

Back

In Hooke's Law, the relationship is linear; as the force increases, the extension of the spring also increases proportionally.
