Household objects shaped like a decagon?
There are no ordinary household objects shaped like a decagon. Some glasses or vases may be decagonal in shape.
Household objects shaped like a nonagon?
There are few household objects that are shaped like nonagons. Some coins in a few countries are, but even these are rare designs.
What is object has an obtuse angle?
some objects that has an obtuse angle is a pentagon, laptop and the objects that is greater than 90 degrees
What aer some objects shaped like a hexagon?
A pencil, quilt block, tiles for the floor, snowflakes, nuts and bolts, honeycomb, chicken wire and soccer ball!
Mathematical design and pattern using Arithmetic progression?
You can best find out how to do this by making a project. Some examples include doing the pendulum bob or making different shapes but changing the sizes.
What is a pengelom?
That is a misspelling of Pendulum. A pendulum is a weight suspended from a pivot so that it can swing freely. Some clocks have this...
Is the ending and starting height of the pendulum exactly the same?
No, the swing of the pendulum will never carry it back quite as high as it was when it started. The pendulum must work against air resistance, and so a little bit of momentum is lost with every swing. Even if the pendulum operated in a vacuum, there would still be some tiny amount of friction at the point where the pendulum is attached to its frame. The swing of a pendulum is never 100% efficient. So the pendulum will run down.
Why does a swinging pendulum lose energy once it is set into motion?
When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.
How can you make a pendulum swing without stopping Is it possible?
Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
What are some examples for a pendulum?
grand father clock, a rocking ship at a ride park, and a swing set.
What was Galileo's greatest scientific discovery?
In my opinion, his greatest discoveries were those about the nature of the solar system. His telescopic observations led to the start of a great revolution in the attempt to understand the nature of the objects in the sky. He discovered moons of Jupiter and the fact that Saturn has a system of rings.He also corrected some misunderstandings about gravity. He proved that a pendulum's period was a factor of the length of the pendulum, not the length of the arc of the pendulum's swing. This led to pendulum clocks. He also postulated and proved that an objects rate of fall when dropped is independent of its weight. It had previously been assumed that heavier object fall faster than lighter objects by nature.He also discovered the unwillingness of the Catholic Church to abandon superstitious dogma in favour of rational scientific thought.
What are some uses of the pendulum?
o Surveyors and construction workers use pendulum (plumb bob) to accurately locate their transits or levels over a specific spot on the Earth's surface o Grandfather clock o A swing in the park o Seismographic instruments use a modification of the basic pendulum
What are some of the dangers of an outdoor swing set?
The dangers of an outdoor swing set change situation to situation. The most common dangers are; falling from swing, collapse of poorly constructed swing, arsenic in treated wood and swinging into stationary objects.
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.
Describe the energy conversions that take place in the pendulum?
In a pendulum, the energy transformations involve potential energy being converted to kinetic energy as the pendulum swings back and forth. At the highest point of the swing, the pendulum has maximum potential energy, which is then converted to maximum kinetic energy at the lowest point of the swing. This process continues as the pendulum oscillates, with energy being continually converted between potential and kinetic forms.
In measuring the period of a pendulum's motion with a stopwatch how could you best minimize the influence of reaction time?
In measuring the period of a pendulum's motion with a stopwatch, you can best minimize the influence of reaction time by measuring period at the maximum swing point, i.e. the point where the pendulum stops and then reverses. It is at that point that the pendulum is moving the slowest. You should also make your line of sight be perpendicular to the swing, in order to minimize parallax error; and you should have a mark of some kind that you can move around to the peak value, then recording the period between successive peak values.
How do you adjust a pendulum on a clock?
The pendulum of a clock is usually constructed with some sort of clamp or sliding catchthat permits sliding the weight up and down the stick, raising or lowering its center of massand thus changing its effective length.-- If the clock is running too fast, and has to be turned back a few minutes every now and then,make the pendulum slightly longer, by sliding the weight down a bit on the stick. This makesthe pendulum swing slightly slower.-- If the clock is running too slow, and has to be turned a few minutes ahead to catch up everynow and then, make the pendulum slightly shorter, by sliding the weight up a bit on the stick.This makes the pendulum swing slightly faster.
