sp15 - forces and elasticity

Question 1

elastically distorted

Answer 1

an object that can go back to its original shape and length after the force has been removed

Question 2

elastic object

Answer 2

objects that can be elastically distorted

Question 3

inelastically distorted

Answer 3

an object that doesn’t return to its original shape and length after the force has been removed

Question 4

elastic limit

Answer 4

the point where an object stops distorting elastically and begins to distort inelastically

Question 5

what is the relationship between force and extension

Answer 5

they are directly proportional

Question 6

spring constant

Answer 6

a measure of the stiffness of a spring up to its limit of proportionality - a stiffer spring has a greater spring constant

Question 7

maximum force

Answer 7

when the extension is no longer proportional to the force

Question 8

what’s it called past the elastic limit

Answer 8

past the elastic limit, the object is permanently stretched
