hooke law Flashcards
What does Hooke’s Law state?
The extension of an elastic object is directly proportional to the force applied, up to the limit of proportionality.
What does directly proportional mean in the context of Hooke’s Law?
As the force is increased, the extension increases.
What happens to the extension if the force is doubled?
The extension will double.
What happens to the extension if the force is halved?
The extension will also halve.
What is the limit of proportionality?
The point beyond which the relationship between force and extension is no longer directly proportional.
What does the force-extension graph represent?
Hooke’s law is the linear relationship between force and extension, represented by a straight line on a force-extension graph.
What is plotted on the y-axis of a force-extension graph?
Force.
What is plotted on the x-axis of a force-extension graph?
Extension.
What is elastic behaviour?
The ability of a material to recover its original shape after the forces causing the deformation have been removed.
What is deformation?
A change in the original shape of an object.
What are the two types of deformation?
Elastic and inelastic.
What is elastic deformation?
When the object returns to its original shape after the deforming forces are removed.
What is the result of elastic deformation?
A change in the object’s shape that is not permanent.
What are examples of materials that undergo elastic deformation?
Rubber bands, fabrics, and steel springs.
