The period of oscillation of a simple pendulum does not depend on the mass of the bob. ... Since the mass factors into both the cause of changing motion and the resistance to changing motion , it cancels out. For a mass-spring system, the mass still affects the inertia, but it does not cause the force.
Does mass influence 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.)
Does mass affect pendulum?
The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.
Does mass not affect the period of a pendulum?
The mass of the bob does not affect the period of a pendulum because (as Galileo discovered and Newton explained), the mass of the bob is being accelerated toward the ground at a constant rate — the gravitational constant, g.
Why does a pendulum eventually 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.
What affects the period of a pendulum?
The mass and angle are the only factors that affect the period of a pendulum.
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.
What does not affect period of a pendulum?
The mass of a pendulum’s bob does not affect the period. ... As mass increases, so does the force on the pendulum, but acceleration remains the same. (It is due to the effect of gravity.) Because acceleration remains the same, so does the time over which the acceleration occurs.
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
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.
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.
Where does energy go when a pendulum stops swinging?
When the pendulum stops briefly at the top of its swing, the kinetic energy is zero , and all the energy of the system is in potential energy. When the pendulum swings back down, the potential energy is converted back into kinetic energy. The truly conserved quantity is the sum of kinetic, potential, and thermal energy.
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.)
What is the purpose of the pendulum experiment?
The goal of this experiment was to determine the effect of mass and length on the period of oscillation of a simple pendulum . Using a photogate to measure the period, we varied the pendulum mass for a fixed length, and varied the pendulum length for a fixed mass.
What is one period of 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.
Which pendulum oscillates faster?
Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right.
