Question

Suppose you have an object tied to a rope and are rotating it over your head in uniform circular motion. If you increase the length of the rope, would you have to apply more or less force to maintain the same speed?

a) More force
b) Less force
c) No change in force
d) Depends on the mass of the object

Answer 1

When you increase the length of the rope while rotating an object over your head in uniform circular motion, you would need to apply more force to maintain the same speed.

Step-by-step explanation:

When you increase the length of the rope while rotating an object over your head in uniform circular motion, you would need to apply more force to maintain the same speed. This is because the force is directly proportional to the radius of the circular orbit.
