Question

1. How does increasing the radius of the circular moving object affect the centripetal ​forces?
2 How does doubling the mass affect the centripetal forces?

3 If radius is increased, then the centripetal force will ______________.

4. If mass is doubled, then the centripetal force will _______________.

5 If the experimental centripetal force is compared to the actual lower force (m2),
the percent error will be affected by uncontrolled forces like
____________________________________________________.

6. How would you expect the Fc to change if the radius is increased? Are they directly or ​indirectly proportional? Why? Did your data show this?

7. Why would you expect to see errors larger for this experiment than for many of th ​​
other experiments? What are some uncontrolled sources of error?

Answer 1

Answer: (1) centripetal force is inversely proportional to the radius of an object moving in a circular form.

Centripetal force = mv^{2}/r.

m=mass, v=velocity, r=radius.

(2). Doubling the mass affect the centripetal force following the fact that the centripetal force is directly proportional to the mass therefore, if the centripetal force increases four times (Radius kept constant), the mass increases two times.

(3) If radius is increased, then the centripetal force will decrease.

(4). If mass is doubled, then the centripetal force will also double.

Step-by-step explanation:

from the above relation, centripetal force is inversely proportional to the radius and is directly proportional to the mass and velocity.

If only the centripetal force is increase and others are kept as it is, then the moving object will gradually move towards the focus point reducing the radius proportional to the increase in centripetal force.

for example:- relating to mass and velocity, if the centripetal force is increase four times, the mass or velocity will increase two times keeping the radius constant for the condition.
