What happens if you hang small weights from a spring?

It will stretch

1 of 14

What is the increase in length from the original called?

The extension

2 of 14

What happens when you remove small weights from a spring?

It will return to its original lenth.

3 of 14

What is an elastic object?

One that regains its original shape when the objects deforming it are removed.

4 of 14

What happens if we plot a graph against force applied on the spring?

It will go through the origin, meaning it is directly proportional to the force applied.

5 of 14

What happens if the line starts to curve?

We have exceed the limit of proportionality.

6 of 14

What is Hooks law?

The extension of a spring is directly proportional to the force applied, provided its limit of proportionality is not exceed.

7 of 14

What is Hooks law equation?

F = k x e

8 of 14

What is 'F'? Units?

F is force applied in newtons.

9 of 14

What is 'k'? Units?

Spring constant in Newtons per metre, N/m

10 of 14

What is 'e'? Units?

Extension in metres.

11 of 14

What happens the stiffer the spring?

The greater the spring constant.

12 of 14

What happens when an elastic object is stretched?

Work is done and stored as elastic potential energy.

13 of 14

What happens when the stretching force is removed?

The stored energy is released.
