Question
Describe what happens to the energy stores in a system when work is done on a material, such as compressing a spring.
Answer
When work is done on a material, such as compressing a spring, energy is transferred to the spring, increasing its elastic potential energy store. This energy is stored as the spring is compressed and can be released when the spring returns to its original shape.
Explanation
This question assesses the student's ability to describe energy changes in a system due to work done. It focuses on the concept of elastic potential energy and requires an understanding of how energy is stored and transformed within a physical system.
Common mistake
Confusing Energy Stores
Students often confuse the decrease of one energy store with the increase in another without understanding the relationship between them.
To fix this, clearly link the concepts by explaining how energy is conserved and transferred between stores, ensuring to illustrate specific examples of energy transformations.
