Two magnets are stuck together when a physics student pulls them apart and holds them close to each other so she can still feel them pulling on each other. How does pulling the magnets apart affect their magnetic potential energy?

A. stays the same
B. decreases by one half
C. magnets cannot create potential energy
D. magnets only have potential energy when they are touching each other
E. increases

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
