Is Tension Higher At The Top Or Bottom?

Tension and gravity are NOT “in the same direction”. The tension in the rope is always directed toward the middle of the circle.

At the bottom

, that means tension is UPWARD while gravitational force is directed DOWNWARD.

Is tension the same at the top and bottom of a circle?

The velocity must increase as the mass moves downward from the top of the circle, subject to the constraints stated. … the tension at the top of the circle

is T

_top

= Newtons

. The corresponding tension at the bottom of the circle is T

_bottom

= Newtons.

Does tension go up or down?

The direction of tension is the pull which is given the name tension. Thus, the tension will point

away

from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.

At which point is the tension maximum?

Tension is minimum at the top and maximum

at the bottom in

a vertical circular motion.

Why is tension least at the top?

So, as the object goes round the circle the tension in the

string varies being greatest at the

bottom of the circle and least at the top. Therefore if the string is to break it will be at the bottom of the path where it has to not only support the object but also pull it up out of it straight-line path.

What happens when tension is 0?

It equals zero because

the weight isn't moving so the acceleration is zero

. … As you can see from the above equation, the tension transmits the force of gravity that acts on the weight, to a force acting on the hand. This is a general feature of massless strings, and is true even if there is acceleration.

Which string is most likely to break?

A)

The upper string

is most likely to break and has more tension due to the force of your pull as well as the weight of the ball. Weight is more important because it determines how much tension is being put on the upper string.

Where is tension greatest in a circle?

tension is greatest at

the bottom of the circular path

. This is where the rope is most likely to break.

Is tension constant in a vertical circle?

Due to the influence of the earth's gravitational field, the magnitudes of the velocity of the body and tension in the string change continuously. It is maximum at the lowest point and minimum at the highest point. Hence the

motion in vertical circle is not uniform circular motion

.

How do you determine tension?

The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object:

T = mg.

What happens if there is no tension on objects like a rope or string?

if there is no tension on object like a rope or a string ,they

will not be straight and will bend

because tension act along the direction of the string . tension is present only if an object is stretched and therefore has no tension ,you can change the direction of the force by changing the direction of string .

Does tension depend on length?

The length will not affect the tension

.” Eight students concluded that the ten- sion in the right string in case A is greater because the string is shorter. … “The tension in the right string in case B would be less than the tension in case A because the weight of the metal is distributed over a longer distance.”

Why is tension constant in a massless string?

The concept of tension in a string can be difficult to grasp because a string is both

non-rigid and extended

, so that the tension exists throughout the string rather than being applied at a single point. To most students the assertion that the tension in a massless string has a constant magnitude is a great puzzle.

How do you find minimum tension?

The centripetal force is always the same but part of this (and a constant part – the weight of the object) is supplied by the gravitation al pull of the planet. (a) The minimum tension is at the top.

Centripetal force = constant (constant speed) = mv

²

/r = 192 N

. The maximum tension is at the bottom.

How do you find the maximum and minimum tension of a string?

1. K. E.= 12mv2.
2. P. E.= mgh.
3. 12mv2=mgl(1−cosθ)
4. ⇒v2=2gl(1−cosθ)
5. Tmax=mg+2mg(1−cosθ)
6. Tmin=mgcosθ
7. mg+2mg(1−cosθ)=2mgcosθ
8. ⇒mg+2mg−2mgcosθ=2mgcosθ

What's the relationship between centripetal force and frequency?

That

relation

tells us that the

centripetal force

is proportional

to

the mass and

to

the radius and proportional

to

the square

of

the

frequency

.
