Identifying centripetal force for ball on string - Khan Academy.

Answer (1 of 7): The other two answers are correct here. If the ball on a string is in uniform circular motion in a horizontal circle, the component of the tension in the direction of the center of the circular path is the centripetal force. That is, the only reason why we refer to "the centripet.

Re: What physical laws are used to keep button spinning on string?.

Figure 1 — Direction of racquet head and spin axis in a kick serve, as viewed by (a) a right hander and (b) a left hander. The ball is traveling into the page toward the net. The spin is primarily sidespin here with a small topspin component. The aerodynamic Magnus force, F, acts at right angles to the spin axis, pushing the ball down onto the court and causing it to curve to the left in (a. The rope and the string doesn't need a centrifugal force because the sting constrains the motion of the length of the string. In this case the centrifugal force does not have to exist but is merely a vector caused by the momentum of the ball and the length of the string. The earth spinning around the sun is different.

45 J (2) Gravitational PE (J) at Bounce Height = mass of ball (kg ) x acceleration/gravity (9. When dropped from the same height a body reaches the ground quicker at poles than at the equator. For a bouncing ball, the action is a ball falling against the ground or "Do balls lose bouncing height at different rates if they are. Spinning wheel on string. Purpose. To illustrate concepts of circular motion such as angular momentum. Parts. The wheel with string attached is found between shelves G and H; Setup. Spin wheel in position perpendicular to floor. Hang it by the string and notice that it stays upright.... Physics Phone Number 413.597.2482 413.597.4116. High school physics; High school physics - NGSS; AP®︎/College Biology;... let's imagine someone spinning a flaming tennis ball attached to some type of a string or chain that they're spinning it above their head like this and let's say they're spinning it at a constant speed. We've already described situations like this, maybe not with as.

Here, we look at the science behind this difficult yet intriguing art. Spin bowling consists of two parts. One, usually the trajectory of ball i.e how it reaches the batsman in the air, and two. Answ: 4.33 m/s. b)The mass, with a new string, is whirled in a vertical circle of the same radius about a fixed point. Find the magnitude of the tension when the mass is at the top if its speed at the top is 6.69 m/s. Answ: 2.45×102 N. For part a) i used the formulaa 1) F=ma 2)a=rw^2 3) V=rw to get the right answer but for part b) I used 1)V.

Friction with the air allows a rapidly rotating loop of string to lift up its unsupported end. Rise up. When pulled through a pair of rollers (top left), a loop of string will rise to an angle that depends on the roller speed, as shown in this composite photo (see video below). Experiments with a loop of string pulled rapidly through rollers.

The ball's motion around the cone. Then the ball's horizontal acceleration is m'Ω2 to the left. So F = ma along the plane gives (where Ff is the friction force) mgsinµ +Ff = m'Ω2 cosµ: (1) Now let's look at ¿ = dL=dt. To get a handle on how fast the ball is spinning, consider what the setup looks like in the rotating frame in. 7,831. shadowfalcon said: True. At the bottom of the circle the net force must point upwards or otherwise center of circle. In order for this to happen, the gravitational force must be therefore less than the tension force exerted upwards. Yes. Jun 28, 2013. #10. kevin17ym. There is no consistent variation in outgoing ball spin with string tension, but there is a clear difference with string type. The average spin for the four new nylon strings (1 to 4) was 122 rad/s, the same as the old nylon string (16)....

The Physics of Swinging a Mass on a String for Fun - Gizmocrazed.

Physics: If you have a ball spinning on a string which is attached to a pole, will it keep spinning in the absence of any friction/air resistance/other retarding forces? I'm trying to think about this in terms of Newton's First Law which suggests that the ball will keep trying to rotate, causing tension in the string ~ Ball suspended on a string.

Prank Mailfly: The bug will fly away to another random point on the page. Well, the office can be a really boring and monotonous environment. In a video demonstrating the magnus effect a basketball with a backspin was dropped from a 400′ high wall. The reverse spin caused the ball to curve away from the wall, and actually appeared to curve away at a faster rate as it dropped. So I wondered if the air flow over the ball actually caused it to spin faster as it fell.

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?. Advanced Physics; Advanced Physics questions and answers; The force of gravity of a ball spinning on a string in a vericle circle of D (diameter) is four times smaller than the tension force at the bottom of the circle. What's the velocity at the bottom, definined in (terms of) physicial constants and D?.

Q: Why does putting spin on a ball change how it moves through the air.

With T = 100 N and mg = 36.26 N, the angle works out to: θ = 21.26 degrees. Either the x-equation or the neat relationship we derived above will then get us the speed. Be careful with r, which is NOT the length of the string. r = 1.40 cos (θ) = 1.305 m. This gives v = 5.73 m/s.

In your question let's assume you're trying to spin.. When the rod/string makes an angle θ with the vertical the mass is moving in a circle with radius r = L sin ( θ) where L is the length of the rod/string. So if the tension in the rod is T we have. T sin ( θ) = m r ω 2 = m L sin ( θ) ω 2 ⇒ T = m L ω 2. Note that since m and L are fixed, T depends only on ω.

Ω 2 = 782 - 0.29ω 1. which means that the outgoing spin is largest if the incoming ball has backspin (then ω 1 is negative). For example, if ω 1 = -300 rad/s, then ω 2 = 869 rad/s = 8298 rpm. That is a huge amount of spin, much larger than is ever observed off the court or off the strings of a racquet. From Newton's second law, T u - T l = m(g-a) where T u is the tension in the upper string, T l is the tension in the lower string, m is the mass of the ball, g is the acceleration due to gravity (9.8 m/s 2) and a is the downward acceleration of the ball. Thus the upper string breaks when the downward acceleration of the ball is less than 9.8 m.

SPINNING TOPS - School of Physics.

In physics, a top is what is known as a rigid body. When a rigid body is fixed at a single point, there is 3 degrees of freedom for its motion. A spinning top in motion: Rotates around its own axis (ie, the spin) Tilts to the side. Rotates around a vertical z-axis. Numbers 2 and 3 may not be noticeable until the top starts slowing down.
