2.6 Streching And Squashing

Question 0

Regarding springs what is an extension

Answer 0

The difference between the length of the spring and its original length

Question 1

What is in inelastic object

Answer 1

And inelastic object is one that does not regain its original shape when the force deforming it are removed

Question 2

What is Hooke’s Law?

Answer 2

The extension of the spring is directly proportional to the force applied provided its limit of proportionality is not exceeded

Question 3

How can we tell when a spring has exceeded its limit of proportionality

Answer 3

The graph of extension against the force applied is no longer a straight line

Question 4

What does directly proportional mean

Answer 4

A graph will show that if the line of best fit is a straight line through the origin

Question 5

Does the limit of proportionality mean

Answer 5

The limit of Hooke’s Law applied to the extension of a stretching spring

Question 6

The stiff in the spring is…

Answer 6

… The greater its spring constant
