In this experiment, a spiral spring is required with different masses. A retort stand and a cork is needed to fix the spring. A meter rule is used to measure the original length and displacement of the spring.
This experiment seeks to demonstrate Hooke's law. Hooke'e law states that, as long as the elastic limit is not exceeded, the force applied is proportional to the extension.
To demonstrate this law, we need;
- A retort stand
- A cork
- A spiral spring
- A meter rule
The set up appears as shown in the image attached. The natural length of the spring is first measured and recorded. The masses are now added gradually and the displacement of the spring is recorded each time.
A straight line graph is obtained when the force is plotted against the displacement within the elastic limit of the spring.
