The work done by this force can be both positive and negative depending on the direction of the displacement relative to the force.**Force of Friction:** This force opposes the motion of the mass, acting in the direction opposite to the velocity at any point. The work done by the friction force is always negative as it always acts in a direction to remove kinetic energy from the system.**Explanation of Energy:**Energy is defined specifically for the restoring force of the spring. This is known as the potential energy stored in the spring, usually referred to as elastic potential energy. The frictional force dissipates energy as thermal energy, which is not stored in the system in a recoverable way.For further inquiries and detailed explanations, please explore the sections:- [Work and Energy Principles](#)- [Oscillatory Motion Dynamics](#)- [Frictional Forces Analysis](#)Feel free to reach out to our educational support team for any questions.
