What factors affect the pendulum?
The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity.
The period is completely independent of other factors, such as mass..
What causes a pendulum to stop swinging?
A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. … The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.
What is the purpose of a pendulum?
Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.
What is the maximum angle of a pendulum?
Paul Appell pointed out a physical interpretation of the imaginary period: if θ0 is the maximum angle of one pendulum and 180° − θ0 is the maximum angle of another, then the real period of each is the magnitude of the imaginary period of the other.
Where does energy go when a pendulum stops swinging?
Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object.
How can you make a pendulum experiment more accurate?
Improve the accuracy of a measurement of periodic time by:making timings by sighting the bob past a fixed reference point (called a fiducial point )sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.
What factors affect the period of a pendulum what property of a pendulum does not affect its period?
The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g, according to The mpeg movie at left (39.5 kB) shows two pendula, with different lengths.
What variables affect the period T of a pendulum?
The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.
What quantity affects the period of a pendulum?
Three factors that we might expect to have an effect on the period are the amplitude of the swing, the mass of the pendulum�s bob, and the length of the pendulum. Using the guidelines below, investigate the amplitude, the mass, and the length independently which is vary one while holding the other two constant.
What forces act on a pendulum?
There are two dominant forces acting upon a pendulum bob at all times during the course of its motion. There is the force of gravity that acts downward upon the bob. It results from the Earth’s mass attracting the mass of the bob. And there is a tension force acting upward and towards the pivot point of the pendulum.
Why doesn’t mass affect a pendulum?
The mass on a pendulum does not affect the swing because force and mass are proportional and when the mass increases so does the force. … 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.
What determines how fast a pendulum swings?
Length. The swing rate, or frequency, of the pendulum is determined by its length. The longer the pendulum, whether it is a string, metal rod or wire, the slower the pendulum swings. Conversely the shorter the pendulum the faster the swing rate.
Does a pendulum tell the truth?
As an example – people use a pendulum to ask if a certain food is good for them by holding it over the item, and if it’s a healthy high vibration food then the pendulum will answer YES.
Where is acceleration greatest in a pendulum?
The Physics The acceleration is a maximum at the end points of the swing, and a minimum (zero) in the middle, at the lowest point. The forces acting are gravity, tension and friction.
How do you keep a pendulum swinging?
There are several things that you can do to make a pendulum swing for a long time:Make it heavy (and, specifically, dense). The more mass a pendulum has, the less outside influences such as air resistance will degrade its swing.Put it in a vacuum. … Use an escapement mechanism. … Give it a large initial swing.
What is one period of a pendulum?
1 A pendulum The period is the time it takes to complete one full cycle. The period of a pendulum is the time it takes for the pendulum to swing from left to right and back again. The amplitude describes the size of the cycle. The amplitude of a pendulum is the amount the pendulum swings away from equilibrium.
Does weight affect the speed of a pendulum?
When you add a weight to the middle of the other pendulum, however, you effectively make it shorter. Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right.
How long will a pendulum swing?
Here is an extra fun fact. A pendulum with a length of 1 meter has a period of about 2 seconds (so it takes about 1 second to swing across an arc). This means that there is a relationship between the gravitational field (g) and Pi.
How does air resistance affect a pendulum?
The air resistance reduces the acceleration and increases the time period of oscillation. … The air resistance reduces the velocity of the pendulum and the pendulum gradually comes to rest.
Why do shorter pendulums swing faster?
Why does the angle the pendulum starts at not affect the period? (Answer: Because pendulums that start at a bigger angle have longer to speed up, so they travel faster than pendulums that start at a small angle.)
Does release angle affect period pendulum?
(Increase the length of the string and increase the angle.) … 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.)
