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.
Does angle affect period of pendulum?
The period of a pendulum does
not depend
on the mass of the ball, but only on the length of the string. … With the assumption of small angles, the frequency and period of the pendulum are independent of the initial angular displacement amplitude. A pendulum will have the same period regardless of its initial angle.
What variables affects a pendulum period?
3 The three pendulum variables
In this experiment, the period of the pendulum is the
dependent variable
. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
What factors do not affect the period of a pendulum?
The time period of the Simple Pendulum is also not depends upon
the Shape or Size of the bob
. Whether, the shape or size is increased or decreased, it will not effect the Time period of the given Pendulum. where, g is the acceleration due to the gravity of the place and l is the length of the string.
How do I keep my pendulum swinging?
Check The “Beat”:
Listen to the tick-tock on the clock
and see if it is nice, even tick-tock. It should sound steady and even like a metronome. You work toward equal time between the TICK and the TOCK. The pendulum needs to swing exactly equal distances from dead center to the left, as from dead center to the right.
What affects the swing rate of a pendulum?
(Mass does not affect the pendulum’s swing. 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.)
Which pendulum will swing faster?
Shorter pendulums swing faster than longer ones do, so the
pendulum on the left
swings faster than the pendulum on the right.
Why does amplitude not affect the period of a pendulum?
Increasing the amplitude means that there is a larger distance to travel, but the restoring force also increases, which proportionally increases the acceleration. This means
the mass can travel a greater distance at a greater speed
. These attributes cancel each other, so amplitude has no effect on period.
Does air resistance affect the period of 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.
What is one oscillation of a pendulum?
One oscillation is completed by a pendulum when it starts from the extreme position A and moves to the other extreme position B and then returns to A. The time to complete one oscillation is called
the time period
. The time period of oscillation remains constant.
What is the time period of a pendulum?
The time taken to complete one oscillation is known as the time period of the pendulum.
Time Period = (Total time is taken)/ (Number of Oscillations)
Given: – 20 oscillations taking 32s to complete. Therefore 1 oscillation will take = (32)/ (20) sec = 1.6 second. Therefore 1.6s is the time period of the pendulum.
What is time period formula?
The formula for time is:
T (period) = 1 / f (frequency)
. λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.
What causes a pendulum to slow down and stop swinging?
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. 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.
Why won’t the pendulum keep swinging?
Have you recently moved your clock? The reason a clock pendulum often stops swinging, after being moved, is because
the clock case now leans at a slightly different angle then it did at its former location
. Don’t worry about making your clock absolutely level with the floor and don’t use a level.
Why does a pendulum keep swinging?
Function. The science behind the pendulum is explained through the
forces of gravity and inertia
. The Earth’s gravity attracts the pendulum. … This swinging-back-and-forth force continues until the force that started the movement is not stronger than gravity, and then the pendulum is at rest again.
How do you tell if a pendulum is saying yes or no?
Here’s an example of how to program the “yes” signal: Holding the pendulum in position, say
“When I ask a question and the answer is yes, move like this, in a clockwise circle
.” (or whatever signal you’ve chose for “yes”).
