Title: Hooke's Law

Aim: To determine the spring constant.

Equipment:

* Retort stand (with clamp)

* Spring (with hook)

* Masses ( 100g, 200g, 300g, 400g, 500g )

* Ruler

Variables:

Independent Variable:

- Changing the mass ? Weight force (F).

Dependent Variable:

- The extension of the spring ?x.

Control Variable:

- "Spring" Dimensions of the spring.

Mass of the spring.

Radius of the spring.

- "Retort Stand" Height of the retort stand.

Method:

1. The spring (its dimensions, mass and its radius) were measured in its initial face.

2. The spring was then place in the clamps of the retort stand and was held together tightly enough to hold it in place.

3. At the end of the spring (where the hook is), a mass of 100 grams was placed and as a result the spring started to extend downwards.

4. Its extension after the weight was placed on the hook was measured using a ruler and compared to its initial face.

5. After five continuous trials with
