A pendulum will swing slowest when closest to the equator. Why is this?
The time period, T, of the swing of a pendulum is given by:
T=2π√(l/g)
where l is the length of the pendulum and g is acceleration due to gravity.
Because the Earth is spinning, there is a bulge at the equator and the poles are
slightly flattened. Hence on the equator the radius to the centre of the earth is
greater than the radius at the poles.
The equatorial radius is 6378.1km while the polar radius is 6356.8 km
The value of g at the Earth's surface relates to the values of the Earth's radius, r, at
that point using an inverse square law ie g is proportional to 1/r2
At the North Pole, g is about 9.83m/s2, while at the equator, g is smaller, at only
9.79m/s2 .
So the period of a pendulum will be longer (i.e. slowest) at the equator than at the
pole
What else can I help you with?
Can perpetual motion be achieved using a pendulum in a vacuum?
Yes. In a vacuum, the only resistance is the friction in the suspension for the bob of the pendulum. Other than that, it should swing a long time. In air, friction with air will add to the friction in the suspension and it won't swing as well as it would in a vacuum. But it will swing for a while. A pendulum will swing in water, but the hydrodynamic drag will make it stop in a really, really short period of time. Just a couple of swings will strip the pendulum of almost all its energy. And the speed of the pendulum will be slower than in air, and it won't swing anywhere nearly as far through the bottom of its arc as it did in air.
What force always tends to slow the motion of an object on a surface?
Friction or gravity .
Why are the plates of the lithosphere in constant slow motion?
The plates of the lithosphere are in constant slow motion due to convection currents in the Earth's mantle. Heat from the Earth's core causes magma to rise, cool, and sink, creating a circular motion that moves the plates. This process is known as plate tectonics.
How many times a year does the sun pass direclty over the equator?
technically it passes twice around the equator each year because the earth moves really slow.
What is a arachute?
Do yo mean Parachute a device used to slow the motion of an object through an atmosphere by creating drag,
Can friction decrease motion?
Yes, friction can decrease motion by acting in the opposite direction to the object's motion, causing it to slow down or come to a stop. This is known as kinetic friction, which opposes the relative motion of two surfaces in contact.
Does a pendulum ever stop swinging?
Yes, a pendulum will eventually stop swinging due to factors such as air resistance and friction, which gradually slow down its motion.
What makes a pendulm swing fast or slow?
The speed of a pendulum is determined by the length of the pendulum arm and the force applied to set it in motion. A shorter pendulum will swing faster, while a longer pendulum will swing slower. Additionally, factors such as air resistance and friction can also affect the speed of a pendulum swing.
How will simple pendulum behave if its taken to moon?
A simple pendulum on the Moon would swing more slowly due to the Moon's weaker gravitational pull compared to Earth. However, the motion would still follow the same principles of a simple harmonic oscillator, with the period of oscillation proportional to the square root of the length of the pendulum.
What factors will cause a pendulum to slow down and eventually stop?
Friction between the pendulum and the air or the supporting point, as well as friction in the pendulum's pivot point, can cause it to slow down and stop. Additionally, if the pendulum loses energy due to collisions or interactions with other objects, it will gradually slow down and eventually come to a stop.
Why would a pendulum eventually stop swinging?
A pendulum stops swinging due to various factors such as air resistance, friction at the pivot point, and loss of energy through heat. Over time, these forces gradually slow down the pendulum's motion until it eventually comes to a stop.
What cause a pendulum to eventually slow down and stop swinging?
A pendulum slows down and stops swinging due to air resistance and friction, which act to dampen its motion. As the pendulum swings, it transfers energy into overcoming these forces, resulting in a decrease in amplitude and eventually causing it to come to rest.
What is the motion of a simple pendulum in air?
No. The pendulum will slow down by drag from air molecules until the motion becomes exactly the same as random motion caused by the air molecules. But I know what you are looking for-- "Isn't there some tiny detectable motion, even if you can't see it?" Let's look at a hanging pendulum that has NEVER been swung. If we tape a tiny mirror to it and bounce a laser beam off it, we will see a spot on the wall that vibrates from thermal (and ignoring environmental) noise. The average motion will NOT be zero in any finite time. BUT the average motion of the pendulum caused by noise will ALWAYS have some positive value depending on temperature (well, okay...zero at absolute zero). When the original swinging pendulum's motion equals the motion caused by random thermal noise, then the motion is ZERO. So it's a much better question than you might have thought! Quantum Mechanically the problem is even more interesting, since there is a small but finite possibility that the pendulum will launch itself into orbit without warning, but it all depends on statistics.
What is fiction how does it affect the swing of a pendulum?
A swinging pendulum follows a simple physical path that is described as simple harmonic motion. A frictionless pendulum would swing forever. Friction generates heat which radiates away energy from the system. Therefore friction will cause the pendulum to slow and stop as all the energy gets removed from the S.H.M. If you rig up a way to replace the lost energy, then the pendulum will continue to swing. This is the method used in a pendulum clock. The energy put into the wind up spring will replace the energy lost due to friction until the spring winds down. The key point is "energy is conserved" which means you cannot create or destroy it. You can only move it from one place to another or convert it into something else.
What is slow motion?
slow motion is when you move slow like in movies.
Does temperature effects the simple pendulum having metallic wire?
Yes, temperature can have an impact on a simple pendulum made with a metallic wire. As the temperature changes, the length of the wire can expand or contract, which can affect the period of the pendulum's swing. This change in length can cause the pendulum to either speed up or slow down.
What would happen if a pendulum is set to swing in vacuum?
In a vacuum, the pendulum would continue to swing back and forth without air resistance to slow it down or stop it. This would result in the pendulum swinging with very little loss of energy over time, creating a more consistent and longer-lasting motion.
