Elasticity and Hooke's law

Question 1

what is elasticity

Answer 1

it is when the object will change its shape or size when a force is being applied

Question 2

what is unstretched length

Answer 2

it is the original length or the total length before applying stretching force.

Question 3

what is stretched length

Answer 3

it is the total length after applying the stretching force.

Question 4

what is extension

Answer 4

it is the difference between the stretched length and the unstretched length

Question 5

how to find the extension

Answer 5

stretched length- unstretched length

Question 6

state hooke’s law

Answer 6

the extension of the spring is proportional to the load applied to it, within the limit of proportionality

Question 7

what is limit of proportionality

Answer 7

upto limit of proportionality the spring will obey hooke’s law. beyond the limit of proportionality the spring wont obey hooke’s law.

Question 8

what is the elastic limit?

Answer 8

up to the elastic limit, the object will return back to its original shape and size when removing the stretching force but beyond the elastic limit, it will not return to its original size and will permanently stretch.

Question 9

what is hooke’s law formula

Answer 9

F=ke(force=spring constant x extension) (f=N, k=N/m, e=m)
