Does speed affect centripetal force?
Mass, velocity, and radius are all related when you calculate centripetal force. The equation shows that if you increase mass or speed, you’ll need a larger force; if you decrease the radius, you’re dividing by a smaller number, so you’ll also need a larger force.
Does tension depend on speed?
It doesn’t even depend on how fast you swing the mass or the string length. That sort of seems crazy, but it’s true. Since the tension in the string is constant and the vertical component of the tension force must be constant, the angle must also be constant.
What does the speed of a wave along a string depend on?
The speed of a wave on a string depends on the square root of the tension divided by the mass per length, the linear density. In general, the speed of a wave through a medium depends on the elastic property of the medium and the inertial property of the medium.
What affects tension in a string?
By Newton’s third law, these are the same forces exerted on the ends of the string by the objects to which the ends are attached. Each microscopic segment of the string pulls on and is pulled upon by its neighboring segments, with a force equal to the tension at that position along the string.
How do you increase the tension of a string?
We will stretch a string across two “bridges”, creating two fixed ends, and then allow the remaining string to hang over a supporting bar with different increments of mass generating its tension. This will allow us to increase tension in the string by the addition of mass, while keeping a constant wavelength.
Why is tension constant in a string?
The tension in the rope is constant if its force does not have to be used to accelerate anything else, including itself. Therefore, if it has negligible mass and is held taut between two points, the tension will be considered constant throughout.
Does mass of string affect tension?
The mass element is in static equilibrium, and the force of tension acting on either side of the mass element is equal in magnitude and opposite in direction. If you pluck a string under tension, a transverse wave moves in the positive x-direction, as shown in (Figure).
Is tension the same everywhere in a string?
The concept of tension of strings is used to explain the transmission of forces from one point to another. For a massless string or cord, the tension is the same everywhere.
What is tension force equal to?
The tension is equal to the mass of the object × gravitational acceleration for suspended objects which are in equilibrium. T= mg. T= tension, N, kg-m/s²
Is tension a non contact force?
Common examples of contact forces are: Friction. Air resistance. Tension.
How do you calculate tension force?
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration.
What happens if there is no tension on object like a rope or a 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 .
Is there a normal force on a hanging object?
4 Answers. “Normal” is a mathematical synonym for “perpendicular”. So the VdW force is a normal force in this case.
Is Tension an electromagnetic force?
The tension in a string is an example of electromagnetic force.
Why tension is an electromagnetic force?
Tension force is due to inter atomic or intermolecular forces in the string ,the ultimate origin of which are electromagnetic forces. When two atoms are far apart, they have some total energy which is sum of energy of individual atom.
Is normal force an electromagnetic force?
The normal force is an everyday force that is felt when a surface pushes against an object that is placed on that surface. The normal force arises from the electromagnetic force; specifically, the electrons in the book push against the electrons in the table.
Is spring force electromagnetic?
Tension and spring forces are the result of similar distortions in the equilibrium subatomic arrangements. Experiments have shown that the electrical and magnetic force are essentially the same fundamental entity, so have been categorically combined into the “electromagnetic” force.
What is the strongest force in the universe?
The strong nuclear force
Why is gravity the strongest force?
Actually, gravity is the weakest of the four fundamental forces. Because they both have mass, the two protons exert gravitational attraction on each other. Because they both have a positive electric charge, they both exert electromagnetic repulsion on each other.
