Aim:
To investigate Hooke’s law for simple springs of rubber
Hypothesis:
The relationship between a load force and a light spring (F=k.x) was first determined by Robert Hooke in the 17th century. Where F is the force applied to the spring, k is the spring constant, and x is the extension of the spring. Hooke’s law states that when an elastic material is subjected to a force, its extension (x) is proportional to the applied force. The value of k is constant for a particular spring.
Variables:
Independent 
Controlled 
Dependent 
Different type of spring used (varied by using different springs) 
Weight of the mass attached (controlled by using only one mass) 
Spring constant Extension by the spring (measure by ruler) 
Materials:
Item 
Quantity 
Accuracy 
Spring with different stiffness
