will a pendulum swing forever?
611145
No pendulum can swing forever because the system loses energy on account of friction. That's why a grandfather clock has to be rewound every few days, to inject a little energy back into the system.

Mass does not affect the period of the pendulum. When looking at the formula for a period of a pendulum, it is " T = 2 (pi) Sqrt (l/g) ". In the formula, "l" is the length and "g" is the force of gravity. Therefore, the mass does not affect the period of the pendulum.

For a given spring and other elastic objects, the extension is directly proportional to the force applied. ... This works until the limit of proportionality is exceeded. When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed.

No. It can not exist. Static or sliding frictions are always there acting on the object. Frictional force and the applied force are always in opposite direction.

Coil springs can and will become compromised after time. However, depending on their application to the vehicle, many coil springs can last the lifetime of the vehicle. There really is no expiration date on coil springs, but there are a few things to check for when inspecting your suspension.

So as long as the energy is conserved, these are valid. Kirchhoff's law is not applicable for time varying magnetic fields as it is based on the assumption that magnetic field does not fluctuate in a closed loop. Normally, these are applied to lumped circuits. ... In this case, KCL and KVL won't be valid.

A: In a short answer, yes. Once you apply a force to an object, it will move. ... So yes, forces will always result in motion, unless there is another force exactly opposed to it.

Once you apply a force to an object, it will move. ... If the answer is zero, as in one force pulling one way and the other pulling the opposite direction exactly, then those forces will basically cancel each other out. So yes, forces will always result in motion, unless there is another force exactly opposed to it.

It's actually part of an original quote attributed to ancient pre-Socratic Greek philosopher Heraclitus of Ephesus: “All is flux; Nothing stays still.” To me, it means nothing is permanent. Everything changes. For example, in a business plan, nothing is set in stone.

From the graph of T2 against l it is clear that they are proportional to each other, that is, the length of the pendulum is proportional to its period squared. The graph is a straight line through the origin. Hence determine a value for the acceleration due to gravity, g.

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)

Brief answer? Yes, the digits of π go on forever without ever repeating. The digits do continue infinitely, but pi is not an infinite number. No, googolplex (the largest officially defined number) is not infinite, even though it is larger than the number of atoms in the universe.

During the oscillations, the total energy of the system (measured in joules) is called the mechanical energy and it's equal to the GPE plus the kinetic energy (KE), which is the energy of motion. A pendulum's mass has its maximum velocity at the bottom of its path; therefore its KE is a maximum and its GPE is 0.

If Q is greater than K, the system will shift to the left. If Q is less than K, the system will shift to the right. If Q is equal to K than the system is already at equilibrium so it will not shift in either direction.

The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial precession). As long as you live on the Earth, these motions remain imperceptible.

A will lasts forever unless the testator revokes it or other conditions are met.

When effective length (L) is constant, the time period (T) of oscillation of a simple pendulum is inversely proportional to the square root of the acceleration due to gravity (g) at a place of observation. So, T∝√1g when L is constant.
