There are different ways to investigate the relationship between force and extension for a spring. In this required practical activity, it is important to:
To investigate the relationships between force and extension for a spring, and the work done in extending the spring.
Record your results in a suitable table.
|Force (N)||Length (mm)||Extension (mm)|
It is important to keep the ruler vertical. Suggest another way to improve the accuracy of the length measurements.
|Equipment falling off table||Heavy objects falling on feet - bruise/fracture||Use a G-clamp to secure the stand|
|Sharp end of spring recoiling if the spring breaks||Damage to eyes and cuts to skin||Wear eye protection and support and gently lower masses whilst loading the spring|
|Masses falling to floor if the spring fails||Heavy objects falling on feet - bruise/fracture||Gently lower load onto spring and step back|
