If a ball swinging in a circle on a string is moved twice as fast the force of the string will be?
If a ball swinging in a circle on a string is moved twice as fast, the tension in the string, which provides the centripetal force, will increase. The centripetal force required is proportional to the square of the velocity; thus, if the speed doubles, the force will increase by a factor of four. This relationship is described by the formula ( F = \frac{mv^2}{r} ), where ( m ) is the mass of the ball, ( v ) is the velocity, and ( r ) is the radius of the circle. Therefore, the force of the string will be four times greater.
What multiplicative factor would you increase tension if you double the speed of a wave on a string?
The speed of the standing waves in a string will increase by about 1.414 (the square root of 2 to be more precise) if the tension on the string is doubled. The speed of propagation of the wave in the string is equal to the square root of the tension of the string divided by the linear mass of the string. That's the tension of the string divided by the linear mass of the string, and then the square root of that. If tension doubles, then the tension of the string divided by the linear mass of the string will double. The speed of the waves in the newly tensioned string will be the square root of twice what the tension divided by the linear mass was before. This will mean that the square root of two will be the amount the speed of the wave through the string increases compared to what it was. The square root of two is about 1.414 or so.
How can you lower the pitch of a note on a quitar by altering then tension of the string?
The pitch is determined by by the frequency in which the string is swinging, which, in turn, is determined by the speed with which a wave can travel through the string. The higher the tension in the string is, the easier it is for a wave to travel through it, and if the speed of the wave increase, so will the frequency, and by default the pitch of the note. And vice versa. If I remember my physics correctly :)
What does the length of a string on a guitar have to do with pitch?
Vibrations run up and down the string at the sound of speed. The longer the string the lower the frequency of the wave biting both ends, resulting in a lower pitch. Frequency is simply the frequency of the vibrations.
A 2 kg ball on a string is rotated about a circle of radius 10 m The maximum tension allowed in the string is 50 N What is the maximum speed of the ball?
15.8 m/s
How can you change how fast a string or rubber band vibrates?
You can change the vibration speed of a string or rubber band by adjusting the tension in the material or by changing its mass. Increasing tension or reducing mass typically increases the vibration speed, while decreasing tension or increasing mass typically decreases the vibration speed.
Does it take an increasing force to cause an increasing speed?
Yes. It is one of the laws of motion (the second law) that says that an object in motion will not change its motion unless acted on by and outside force. You'll have to add more foce to cause the object to speed up. Correction: No. The key word in the question is "increasing." A constant force will cause a constant rate of acceleration. Increasing force will cause an increasing rate of acceleration.
What happens to the speed of an object as an unbalanced force acts on it?
When an unbalanced force acts on an object, it will cause the object to accelerate in the direction of the force. This acceleration will cause the speed of the object to change over time, either increasing or decreasing depending on the direction of the force.
By increasing your speed you also increase?
Force of impact.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
What is two instances does power output become greater?
Power output can become greater by increasing the force applied to an object or by increasing the speed at which the force is applied. Increasing either force or speed, or a combination of both, can result in an increase in power output.
What changes occur in position direction and speed of an object when it is acted on by an unbalanced force?
the rate of change of momentum is directly proportional to the net disbalanced force and occurs in the direction in which the force acts - (newton's 2nd law) basically, it accelerates in the direction of the net force acting on the body.
What force do you need to change speed?
The most basic equation in physics, which was formulated by Isaac Newton, is force equals mass times acceleration. So the amount of force that you need to change speed depends both on the mass of the object whose speed you are changing, and the amount of the change in speed.
How does increasing the speed of an object change its momentums?
Increasing the speed of an object will increase its momentum as well (momentum=mass*velocity).
Why does mud attached with the wheel of a vehicle sprinkled away more if its speed increases?
An object moving in a straight line needs to have a force applied to it for it to change direction. A faster object requires a stronger force to change its direction by the same amount in the same amount of space as you did with the lower speed object. Imagine swinging a stone on the end of a piece of string around your head. The stone is moving in a circular motion and therefore it is always changing direction. The string is pulling the stone in a circular motion and is therefore acting as a force. Now the string can only take so much force so if you speed up the stone, the string has to apply more force to the stone in order for it to be changing direction all the time. Once the stone is going fast enough, the string will not be able to provide enough force and will break and the stone will fly off at a tangent. Think of the "stickiness" of the bits of mud as the string. As you speed up the wheel, the string (stickiness) breaks because it cannot provide enough force to keep the mud moving in a circle. If you're interested in this kind of stuff you should study mathematics which covers circular motion in the mechanics section
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
