elastic potential energy

Question 1

what is elastic potential energy?

Answer 1

the energy stored in a springy object when you stretch or squash it. the work done you do is stored in the object as elastic potential energy

Question 2

what is the equation for elastic potential energy?

Answer 2

elastic potential energy = 0.5 x spring constant x extension²
Ee = 0.5ke²

Question 3

what is the equation for the spring constant?

Answer 3

spring constant = elastic potential energy / 0.5 x extension²
k = Ee / 0.5e²

Question 4

what is the equation for the extension?

Answer 4

e = √Ee / 0.5k

Question 5

what is elastic potential energy measured in?

Answer 5

joules (J)

Question 6

what is the spring constant measured in?

Answer 6

N/m

Question 7

what is the extension measured in?

Answer 7

metres (m)

Question 8

if the spring constant is high, what does it mean?

Answer 8

that the object is hard to stretch or squash

Question 9

if the spring constant is low, what does it mean?

Answer 9

that the object is easy to stretch or squash

Question 10

what is the abbreviation of elastic potential energy used in the equation only?

Answer 10

Ee
