Hookes Law S1 Physics

Front

What is Hooke's Law?

Back

Hooke's Law states that the extension of a spring is directly proportional to the force applied to it, as long as the elastic limit is not exceeded.

Front

What is the SI unit of Spring constant?

Back

N/m (Newton per metre)

Front

What is the SI unit of Force?

Back

N (Newton)

Front

What happens when a material reaches its elastic limit?

Back

Hooke's Law fails, and the material may not return to its original shape.

Front

What does the spring constant represent?

Back

The spring constant (k) measures the stiffness of a spring; a higher value indicates a stiffer spring.

Front

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

Back

The extension of a spring is proportional to the force applied.

Front

If a spring is stretched beyond its elastic limit, what occurs?

Back

The spring may become permanently deformed and will not return to its original length.

Front

What is the formula for Hooke's Law?

Back

F = k * x, where F is the force applied, k is the spring constant, and x is the extension.

Front

What does 'elastic limit' mean?

Back

The elastic limit is the maximum extent to which a material can be stretched without permanent deformation.

Front

What happens to the spring constant as a spring is stretched?

Back

The spring constant remains constant as long as the elastic limit is not exceeded.
