Spring Constant

Question 1

What are signs that something is elastic:

Answer 1

it can:
compress
stretch
bend

and still return to its original shape.

Question 2

When an object changes shape, we say that it has been…

Answer 2

deformed.

Question 3

Elastic deformation =

Answer 3

if the thing returns to its original shape after being deformed, then we call it elastic.

Question 4

Inelastic deformation =

Answer 4

if the thing remains deformed in some way after it has been deformed, then it is inelastic or plastic.

Question 5

Extension meaning:

Answer 5

increase in length of a spring when it is stretched - measure of how the spring’s length changes as we add a downwards force.

Question 6

Spring constant =

Answer 6

how many newtons it would take to stretch the object by 1m.

Question 7

The force applied to a spring is always directly proportional to the extension. However, how much the extension will increase each time depends on its —– ———–

Answer 7

spring constant

Question 8

If you stretch an object too much it can pass its…

Answer 8

elastic limit or limit of proportionality so it will lose its elasticity and become plastic.

Question 9

What is elastic potential energy?

Answer 9

Energy transferred to an object as its stretched.
