Is centripetal force inversely or directly proportional to radius of circular path?
It all depends on the situation. There are two equations which we often use to describe centripetal motion.
The first is F=mw2r
and F=mv2/r
If the angular velocity is constant, say for example you want to compare the centripetal force of a coin resting on a turntable that is 5cm from the centre with one that is 10cm from the centre. Then you should use the first equation. w is the angular velocity which is constant in this situation.
If you want to find out which has the largest centripetal force of cars going round a roundabout at the same speed then you would use the second equation. The tighter the circle the greater the centripetal force.

How is velocity and the radius related to the centripetal acceleration?
Centripetal acceleration is directly proportional to velocity squared and inversely proportional to the radius of the circular path. This means that as velocity increases, centripetal acceleration increases, and as the radius of the circle increases, centripetal acceleration decreases.
Factors that affect tha increase of centripetal force in uniform circular motion?
Centripetal force increases with an increase in the speed or radius of the circular motion. It is inversely proportional to the radius of the circle and directly proportional to the square of the velocity. Generally, any factor that increases the velocity or decreases the radius will increase the centripetal force.
What are the factors affecting the centripetal force of a whirling body?
The factors affecting the centripetal force of a whirling body include the mass of the body, the velocity at which it is moving, and the radius of the circular path it is following. Additionally, the centripetal force is directly proportional to the square of the velocity and inversely proportional to the radius of the circular path.
What is the relationship between centripetal acceleration and angular velocity in circular motion?
In circular motion, centripetal acceleration is directly proportional to angular velocity. This means that as the angular velocity increases, the centripetal acceleration also increases.
What will happen to centripetal force if both speed of body and radius of its circular path are doubled?
If both the speed of the body and the radius of its circular path are doubled, the centripetal force required to keep the body moving in a circular path will quadruple. This is because centripetal force is directly proportional to the square of the speed and inversely proportional to the radius of the circular path.

What is directly and inversely proportional relationship?
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
What is the relationship between centripetal force and velocity in circular motion?
In circular motion, centripetal force is the force that keeps an object moving in a circle. The centripetal force is directly proportional to the velocity of the object in circular motion. This means that as the velocity of the object increases, the centripetal force required to keep it moving in a circle also increases.
How are current and resistance related are they directly proprtional or inversely proportional?
inversely proportional
What happend to centripetal force if the velocity doubles?
If the velocity of an object doubles, the centripetal force required to keep it in circular motion also doubles. This is because centripetal force is directly proportional to the square of the velocity.
What happens to centripetal force if the mass doubles?
If the mass doubles, the centripetal force required to keep the object moving in a circular path will also double. This is because centripetal force is directly proportional to the mass of the object.
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
The statement that current is directly proportional to voltage and inversely proportional to resistance is known as whose law?
The statement current is directly proportional to voltage and inversely proportional to resistance is known as Ohm's Law.
