Which of these forces has a potential energy associated with it?
AViscous force
BSpring force
CSliding friction
DAir drag force
Answer & Solution
Correct answer: B. Spring force
1. A potential energy exists only for a conservative force.
2. Friction and drag dissipate energy instead.
3. The spring force is the conservative one here.
