When you whirl an object on a string and the string breaks what happens to the object?
The tension, caused by the limited length of the string, adds another vector to the rock’s motion, pulling its resultant vector continually inwards from the tangential component. If the string breaks, the centripetal force can no longer act on it, and the inward pull disappears.
When you whirl a can at the end of a string in a circular path?
When you whirl a can at the end of a string in a circular path, what is the direction of the force that acts on the can? The force is toward the center of the circle.
When you whirl a can at the end of a string the centripetal?

What happens if you are swinging a ball on a string in a circle and you release the string?
By swinging the ball(s) in a horizontal plane and then releasing it (them), you can show that the ball(s) would fly off along a straight line if it (they) could – tangent to its (their) circular path at the point of release, but that the string provides a centripetal acceleration, which keeps it (them) moving around in …
What is the force that causes clothes to move in a circular path during the spin cycle of a washing machine?
So “centrifugal force gets your washing dry because it makes the water fly out” becomes “Centripetal force between your clothes and the inside of the drum pushes them around in a circle. There’s nothing to give the water the same kind of push because it can slip straight through the drum holes.
What path would you follow if you fell off the edge of a rotating merry go round?
If you lose your grip on a rapidly-spinning, circular, merry-go-round, you will fly off tangent to the merry-go-round. On the merry-go-round, your velocity is a tangential velocity – your direction is tangent to the circle that you are moving in, at every instant.
What kind of speed would she have at the center?
What kind of speed would she have at the center? Rotational speed: The number of rotations or revolutions per unit of time; often measured n rotation or revolutions per second or per minute (RPM). The lady bug has the same rotational speed anywhere on the record.
Why does a tin can whirled on the end of a string move in a circle?
Centripetal means “toward the center.” centripetal force. If you whirl a tin can on the end of a string, you must keep pulling on the string—exerting a centripetal force. The string transmits the centripetal force, pulling the can from a straight-line path into a circular path.
Is centripetal force equal to tension?
When a car drives around in circles on level ground, the centripetal force is a frictional force. When we whirl a ball around on a string, the centripetal force is a normal force of the string on the hook it’s tied to, and the magnitude of this normal force is equal to the tension in the string.
What kind of force causes a whirling can to break?
When a rock tied to a string whirled in a horizontal circle somehow doubles in mass but keeps the same speed, the string tension _______. If the string that holds a whirling can in its circular path breaks, what kind of force causes it to move in a straight- line path: centripetal, centrifugal, or no force?
What happens when you Whirl a rock on a string?
The rock will continue along the path that it had at the moment the string broke. Newton’s laws indicate that an object in motion tends to stay in motion, unless acted upon by another force. We could reverse this concept to say that a force acts to change the motion of a body.
Why does a rock follow a straight line?
In the case of circular motion, the rock wants to travel in a straight line, and a constant application of force is necessary to constantly change the rock’s direction (into what appears to be a circle, although any other path would be equally viable).
Where is the vertical line through the center of gravity?
A vertical line through the center of gravity of your body is in front of the tips of your toes, which is outside your support base. When you whirl a can at the end of a string in a circular path, what is the direction of the force you exert on the can?
