Question
A spring is compressed by 0.5 m and has a spring constant of 150 N/m. What is the force exerted by the spring Explain your answer using Hooke's law and spring constant and force.
Answer
The force exerted by the spring is 75 N.
Explanation
A strong answer should address calculate force from spring constant and extension directly. Use the context of Hooke's law and spring constant within Forces and elasticity, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps elastic and plastic deformation distinct, and links the conclusion back to the approved learning objective.
Common mistake
Common Mistake in Hooke's Law Calculations
Students often confuse the spring constant and extension values, leading to incorrect force calculations.
Always ensure to clearly identify and label the spring constant (k) and the extension (e) before substituting them into the formula F = k x e.
