hook's law theory.

Question 1

what’s extension?

Answer 1

stretched length with force applied- it’s original length with no force applied.

Question 2

what does hook’s law sate?

Answer 2

extension of a spring is directly proportional to the force applied to it.

Question 3

formula =?

Answer 3

F= K × e

Question 4

in the formula: F= K × e
what does K and e =

Answer 4

k= the spring constant of the spring (N/m)
e=extension (in m)

Question 5

spring constant: what is it a measure of?

Answer 5

how stiff a spring is.

Question 6

spring constant: what decides how big the spring constant is?

Answer 6

stiffer the spring the larger the constant.

Question 7

spring constant: if the spring is stiffer what does that suggest about the force needed to be applied for it to be stretched a given amount?

Answer 7

larger force is needed.

Question 8

spring constant: how does the stiffness of a spring effect the work needed to be done to stretch it a given amount?

Answer 8

stiffer the spring the more work is needed.
