Hooke's Law

Question 1

what is the relationship between the extension of an elastic object and the applied force defined by

Answer 1

Hooke’s Law

Question 2

what does Hooke’s Law state

Answer 2

the extension of an elastic object is directly proportional to the force applied, up to the limit of proportionality

Question 3

what does directly proportional mean in terms of springs

Answer 3

the more force that is applied, the greater the extension

Question 4

what is the limit of proportionality

Answer 4

if more force is added, the object may extend but will not return to its original shape when the force is removed (it will be inelastically deformed)

Question 5

how is Hooke’s Law represented on a graph

Answer 5

a straight line on a force-extension graph

Question 6

what is the relationship between force and extension once a material is beyond its limit of proportinallity

Answer 6

non-linear

Question 7

what are the two ways in which the deformation of a shape can be

Answer 7

elastic or inelastic

Question 8

when does elastic deformation occur

Answer 8

when objects return to their original shape when the stretching force is removed

Question 9

what are some examples of materials that undergo elastic deformation

Answer 9

rubber bands, fabrics, and steel springs

Question 10

when does inelastic deformation occur

Answer 10

when objects remain stretched and do not return completely to their original shape even when the stretching force is removed

Question 11

what are some examples of materials that undergo inelastic deformation

Answer 11

plastic, clay, glass
