Displacement and the Spring Force (Fs) - Hooke's Law

Front

Who discovered Hooke's law?

Back

Robert Hooke

Front

Hooke's Law describes the behaviour of which kind of material under tension?

Back

Elastic materials

Front

A spring has a spring constant of 330 N/m. How far is the spring compressed if 150 N of force are used?

Back

0.45 m

Front

A force of F=500 N is applied to extend a spring. What is the extension x of the spring if its spring constant is k= 500 N/m?

Back

1 m

Front

_________ is the unit of Spring Constant

Back

N/m

Front

What is Hooke's Law formula?

Back

F = kx, where F is the force applied, k is the spring constant, and x is the displacement.

Front

What does the spring constant (k) represent?

Back

The stiffness of the spring; higher values indicate a stiffer spring.

Front

If a spring is compressed by 0.2 m and has a spring constant of 200 N/m, what is the force exerted by the spring?

Back

40 N (using F = kx).

Front

What happens to the spring force when the displacement is doubled?

Back

The spring force also doubles, according to Hooke's Law.

Front

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

Back

Directly proportional; as force increases, displacement increases.
