centripetal force?

Question

from lab involving spinning a stopper on string with varying dangling mass...

briefly explain the relationship between the centripetal force an the amount of hanging weight.

Answer 1

Centripetal force is the force required to cause the object to maintain a circular path (and not fly off in a straight line). F = ma and "a" (acceleration) depends on the string length and how fast you are swinging it. (F is force, m is mass).

Answer 2

although it is true that Centripetal force is the net force of a object moving in a circle, Centripetal force does not just rely on the mass and the acceleration; in fact, it can be said that the mass does not even matter to the centripetal force. Take highway offramp, speeds aren't posted different for small cars compared to trucks, a very large truck on sheer ice could navigate the turn even in icy conditions (due to the posted speed having a 100% safety margin, and also pure physics). The Centripetal force, depending on the situation, could be cause by gravity, tension, components of gravity, or even friction.

Answer 3

First i might desire to remark that your formula isn't valid. F = (m* V * V )/R there is not any "g" interior the equation itself. in F = m a, F is the consequent stress. this is mechanically used. there could be many utilized forces yet while an merchandise speeds up then all of us understand the consequent of all of them prepare. in addition in a circle. If it strikes in a circle then F = m a ( as a vector) and F = m v^2 /r wisely shows the consequent stress mandatory to reason this action. no count how many guy or woman forces that are utilized all of us understand the effectual effect of all of them prepare. The term for this resultant stress is centripetal stress. that's extremely genuine. And the term might want for use because of fact it wisely describes the placement. even although the terminology isn't consistently used precisely. contained in terms of the airplane, the full of all different forces will equivalent centripetal stress if the airplane is moving in a circle with consistent speed. It "balances" in basic terms interior the way that the left hand edge of any "equals sign" balances the main magnificent hand . edge. contained in terms of letting the ball bypass, you get rid of the stress of the string so which you're actually not any extra forcing the ball to pass in a circle. for this reason the ball might desire to pass in a right this moment line at consistent speed. this is the equivalent of struggling with pushing something. It keeps in a right this moment line at consistent speed merely as your ball does once you end pulling it. ( See Newtons regulations). Centrifugal stress is a stress that seems to be recent. it form of feels as though an merchandise is pulling outwards. that's considered that this is untrue. If an merchandise is definitely attempting to pass outwards ( a favorable cost being repelled by using a nucleus as an occasion) then it speeds up without postpone outwards as quickly as the different forces are bumped off. this is not the case for the ball So centrifugal stress isn't maximum magnificent besides the fact that if there might nicely be situations the place that's a useful fiction..

Answer 4

Darkking is right. If the weight isn't moving up or down, then the centripetal force is = weight. If the weight is moving up, then the centripetal force is greater than the weight, etc.
