Can centripetal force be equal to weight?
If the only forces acting on a body are centripetal and weight (C and W) and that body under consideration is not moving such that acceleration a = 0, then f = ma = 0 = C + W; so that C = -W, the centripetal force must be equal and opposite to the weight.
Is centripetal force equal to force?
The centripetal force, the action, is balanced by a reaction force, the centrifugal ( center-fleeing ) force. The two forces are equal in magnitude and opposite in direction. The centrifugal force does not act on the body in motion; the only force acting on the body in motion is the centripetal force.
Is centripetal force always equal to gravity?
Is centripetal force equal to gravitational force? – Quora. No. Centripetal force is defined as the force necessary to maintain an object (with a certain mass) in circular motion (with a certain radius).
Does Mass matter in centripetal force?
We can see that mass does not play a role in the centripetal acceleration of an object, so no matter what happens to the mass, the centripetal acceleration remains the same.
Why should the weight of the counterbalance be equal to the centripetal force?
Bottom line, if a body is not accelerating (stopped or uniform velocity) the sum of ALL forces acting on it must be zero so that f = ma = 0. And that’s why centripetal force and weight are “equal” in your case.
Why is force equal to weight?
Gravitational definition “The word weight denotes a quantity of the same nature as a force: the weight of a body is the product of its mass and the acceleration due to gravity.” This resolution defines weight as a vector, since force is a vector quantity.
What happens when centripetal force is equal to centrifugal force?
Centripetal force and centrifugal force can’t cancel each other because they both are same force depending upon the frame of reference.
How is centripetal force equal to gravitational force?
In the special case of the Earth’s circular motion around the Sun – or any satellite’s circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them. Centripetal forces are always directed toward the center of the circular path.
Is centripetal force equal to centrifugal force?
“Centripetal force and centrifugal force are really the exact same force, just in opposite directions because they’re experienced from different frames of reference.” If you are observing a rotating system from the outside, you see an inward centripetal force acting to constrain the rotating body to a circular path.
How does weight affect centripetal force?
Mass, velocity, and radius are all related when you calculate centripetal force. The equation shows that if you increase mass or speed, you’ll need a larger force; if you decrease the radius, you’re dividing by a smaller number, so you’ll also need a larger force.
What is the relationship between centripetal force and mass?
That relation tells us that the centripetal force is proportional to the mass and to the radius and proportional to the square of the frequency.
How are weight and centripetal force related?
Centripetal mean toward the center. So whenever an object is experiencing the force of gravity due to the earth, the centripetal force is equal to its weight.
