Question

9: If an object is traveling in uniform circular motion at a constant speed, it is ________.

floating

accelerating

decelerating

10: If an object were traveling in uniform circular motion and then doubled its speed, what would happen to the amount of force required to keep it traveling in the same circle?

Answer 1

accelerating, change in direction is considered accelerating

the force needed would be doubled,  f=ma

so if a changes to 2 then the f must increase by double also

Answer 2

9. Accelerating

10. The force would have to be quadrupled.
