What factors affect the period of a pendulum? The

mass and angle

are the only factors that affect the period of a pendulum.

Does weight Affect pendulum period?


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 does mass affect period?


Mass is found to have no effect on the period

. The period is found to increase roughly as the square root of the length, in agreement with theory. The period increases slowly in a complex manner with amplitude.

How does friction affect the period of a pendulum?

Air Resistance/Friction

Each swing encounters that resistance and it

slows down the swing

, although it might not be enough to be noticeable during one swing. Friction also slows down the swing. If the pendulum is swinging based upon inertia from the initial release eventually it will come to a stop.

How does mass affect period of oscillation?

A stiffer spring with a constant mass decreases the period of oscillation.

Increasing the mass increases the period of oscillation

. For example, a heavy car with springs in its suspension bounces more slowly when it hits a bump than a light car with identical springs.

Gravity is constant, suggesting that the only way to manipulate the period of the pendulum is by adjusting the length of the string.

Doubling the length of the pendulum arm

would therefore increase the period.

The mass of a pendulum’s bob

does not affect the period

. Newton’s second law can be used to explain this phenomenon. In F = m a, force is directly proportional to mass. As mass increases, so does the force on the pendulum, but acceleration remains the same.

and so

the motion of the pendulum does not depend on its mass

. Show activity on this post. TLDR: Restoring force (force of gravity) is dependent on mass, so mass cancels out in F=ma.

Bigger mass means you would get more period because there’s more inertia, and it’s also affected by the spring constant.

Bigger spring constant means you’d have less period because the force from the spring would be larger

.

mass has no affect on a period of a pendulum because

all masses fall at the same rate ( -9.8m/s ^2) on earth
