Answer the following question: Q: In harmonic motion there is always what force, which acts in the opposite direction of the velocity? Read this paragraph and choose the correct option from the provided answers: In harmonic motion there is always a restorative force , which acts in the opposite direction of the velocity. The restorative force changes during oscillation and depends on the position of the object. In a spring the force is the spring force; in a pendulum it is the component of gravity along the path. In both cases, the force on the oscillating object is directly opposite that of the direction of velocity. Choices: - magnetic force - inorganic force - locomotion force - restorative force A:
Answer:
restorative force
