Hooke’s law

The title of the Project: Hooke’s law

Purpose of the work:

  • Identify the dependence of elastic force on the displacement of the spring;
  • Identify the dependence of elastic force on the spring’s constant.

Expected results:

  • Elastic force is directly proportional to the displacement of the spring and to the spring’s constant.

Practical part

To run the virtual experiment choose “Intro”.

This is how the virtual lab looks like.

Part 1. Proving Hooke’s law

Virtual experiment.

Step 1. Let’s apply some force and see what happens. The spring gets stretched for some displacement. 

Step 2. Increase the force and see if the displacement increases as well. 

Step 3. Repeat the previous step. Indeed, the Hooke’s law is confirmed that elastic force is directly proportional to the displacement.

Step 4. Now compress the spring with some force, the spring gets displaced. If you increase the amount of applied force the displacement increases as well. 

Part 2. Dependence of elastic force on spring’s constant

Virtual experiment.

Step 1. Take 2 springs with different spring constants. 

Step 2. Apply the same amount of force on both and compare displacements.

Step 3. Increase applied force to the spring with higher spring constant until both displacements are equal. Make a conclusion. 

Conclusion

The Hooke’s law is confirmed, elastic force is directly proportional to the displacement of the spring and spring constant.
