If one used a stiff vertical spring rather than a regular one what would be the results?
The gravitational PE and the Elastic PE would decrease. Am i right?
Yes, you are correct. If one used a stiff vertical spring instead of a regular one, the results would be as follows:
1. Gravitational Potential Energy (PE): The gravitational potential energy would decrease because a stiff vertical spring would exert a stronger force to counteract gravity. As a result, the object connected to the spring would not stretch as much, reducing its potential energy due to gravity.
2. Elastic Potential Energy (PE): The elastic potential energy would also decrease because a stiff vertical spring has a higher spring constant. The spring constant determines how much the spring stretches or compresses under a given force. With a higher spring constant, the stiff vertical spring would not stretch or compress as much as a regular spring for the same applied force. As a result, the elastic potential energy stored in the spring would be lower.
In summary, both the gravitational potential energy and the elastic potential energy would decrease when using a stiff vertical spring instead of a regular one.
