Hooke's Law

Front

What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the amount it is stretched or compressed, as long as the limit of elasticity is not exceeded. This can be expressed as F = kx, where F is the force, k is the spring constant, and x is the displacement.

Front

What is the formula to calculate the spring constant (k)?

Back

The spring constant (k) can be calculated using the formula k = F/x, where F is the force applied to the spring and x is the displacement (extension or compression) of the spring.

Front

If a spring extends 1.5m under a load of 10N, what is its spring constant?

Back

6.7 N/m

Front

What is the unit of spring constant (k)?

Back

The unit of spring constant (k) is Newton per meter (N/m).

Front

How do you determine the extension of a spring when a force is applied?

Back

To determine the extension of a spring, use Hooke's Law: x = F/k, where F is the force applied and k is the spring constant.

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.

Front

What does a low spring constant indicate about a material?

Back

A low spring constant indicates that the material is flexible and can be easily stretched or compressed with a small force.

Front

If a spring has a spring constant of 5N/cm, what is its extension when loaded with 15N?

Back

3 cm

Front

How far is a spring compressed if it has a spring constant of 330 N/m and a force of 150 N is applied?

Back

0.45 m

Front

What is the displacement of a spring if a force of 500 N is applied and its spring constant is 540 N/m?

Back

0.93 m
