Ball on a String | Department of Physics and Astronomy.

Copoly strings—slippery and stiff—generate more spin not because of more friction, but because of less. "The old argument was that the better the grip between the strings and the ball, the more. The key here is in the difference in position between the shadow and the ball. Suppose you could see the ball from the side (instead of from above). Here is a diagram showing the location of the.

Ball on a String Spinning in a Vertical Circle - Physics Forums.

Anybody that has played baseball knows that when you have a fastball that is pitched, it comes in and it is also spinning. Now, the pitcher is not necessarily trying to put spin on it, but just the act of throwing it imparts some spin to it. In general, this spin is put on the ball in such a way that it makes the ball rise. Then the formula for tension of the string or rope is. T = F = m v 2 r. \small {\color {Blue} T=F=\frac {mv^ {2}} {r}} T = F = rmv2... When the string helps to hang an object falling under the gravity, then the tension force will be equal to the gravitational force. If an object of mass m is falling under the gravity, then the tension of. This can be explained by examining possible effects of each of the three variables: the length of the string, the mass of the bob, and the angle displaced. The length of the string affects the pendulum's period such that the longer the length of the string, the longer the pendulum's period.

Ball Spinning on String | Physics Forums.

.. The ball feels a force from gravity and an equal and opposite force from the string. When you start spinning the ball over your head, you are making the ball want to go to the right or the left. But as soon as the ball goes too far to the right or left, the force on the string pulls the ball back to you.

Can you explain to me why is a ball on a string... - UCSB Science Line.

By Newton's 3rd law, if the ball is pulled up by the string, the string will be pulled down by the ball. Fc = -112N So the total net force acting on the string, which is the tension in the string, is… FT = -34N + -112 N = -146N = -1.5e2 N This force is bigger than the weight of the ball alone, so maybe the string will snap. The forward rotation disrupts air pressure around the ball, creating a zone of high pressure above the ball and low pressure below—the same forces that are at work on a bat-breaking baseball pitch..

How is a ball on a string like a planet in its orbit? - Answers.

How can I explain the forces acting on the ball and its motion using Newtonian physics? I have no problem explaining the circular motion when the string is at an angle with the vertical and the plane of the motion is a horizontal that is below the point of suspension: The force in the string and the gravitational force creates a "net force. Imagine spinning a ball on a string around you. The ball is traveling in a circular path. But Newton's first law states that an object in motion stays in motion and that motion is in a straight path, not a circular path. Since the ball is traveling in a circular path, an outside force must be acting on the ball - that force is the string. It is performed by angling the face of the racquet down and hitting the ball from below and brushing it upwards while accelerating the hit. Some racquets like the Wilson Pro Staff 97LS , the Blade 98S or the Prince Warrior 100T ESP with a extreme 14m x 16x string pattern among others , are designed with spin effect by making a wider string pattern, this lets the string bed deflects more and gives the ball added RPM.

Centripetal Force on a Spinning Cup | Department of Physics - Virginia Tech.

Physics; Physics questions and answers; A ball on the end of a string is spinning in a vertical circle. The ball's position at two points, along with its direction of motion, is shown in the figure below. Which of the following forces acting on the ball never contributes to the net force required to keep the ball moving in a circle?.

Lesson 31: Vertical Circles - Studyphysics.

.. The circular acceleration would be the product of the angular velocity squared (we like to use the symbol ω for this) and the radius of the circle. Notice that the radius of the circle is not the length of the string—instead it is the length of the string multiplied by the cosine of θ (to get that adjacent side of the triangle).

Centripetal Force on a Spinning Cup. Centripetal Force on a Spinning Cup principles in circular motion by having a cup of water seemingly defy gravity. The demonstration is used to explain centripetal acceleration, and a central force. While this demonstration takes some practice, it is one of the most fun and rewarding demonstration we have. The outgoing spin of a ball therefore depends mainly on the parameters of the incoming ball (i.e., its speed, spin and angle). The dependence on string type and tension are smaller effects, and are not easy to measure. Most of the rebound spin data was obtained with clamped racquets and with v1 = 23 ± 2 m/s, θ1 = 40° ± 2° and ω1 = -400 ± 30 rad/s.

L= mVr(sin theta) Law of Angular Momentum says that the velocity of the ball with respect to the angle and the mass of the ball, that is we decrease the mass or make the angle tighter, then the object will spin faster. IE: Imagine your standing on a disk that has free circular. It's the string providing the centripetal force that causes the ball to go in a circular path. We don't need another force to go in the opposite direction, because that would cancel out the centripetal force, causing no acceleration. That doesn't make sense, because the ball is accelerating (changing direction, therefore changing velocity). The ball is the planet in orbit, the person twirling it is like the sun. the string is the gravitational pull between the two, while the orbital velocity of the ball tries to escape (if you let.

Will a ball on a string spin around its own axis when... - Physics F….

The ball spins out of the strings in back and into the strings in front. The braking motion of friction causes the top half of the ball to stretch forward as momentum shifts weight forward. The combination of spin and braking moves the net normal reaction force (the sum of all the individual forces) in front of the center of mass by an amount D.. At. 7:28. in the video, he writes down Newton's 2nd Law in the x-direction, which is the direction that is toward the center since the circle is horizontal. So we see that the centripetal force in this case is the horizontal component of the tension, Tx = Tsin (30). That is the only force in the horizontal plane, so that is equal to the mass.
