The period of a mass m on a spring of spring constant k can be calculated as
T=2π√mk T = 2 π m k .
What is the equation for period?
each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is
T = 2π Square root of√
L
/
g
, where L is the length of the pendulum and g is the acceleration due to gravity.
How do you find the mass of a spring?
(Here, the term “spring force” means the force exerted by the spring on the object attached to it. The object is often called the “mass.” Mathematically,
F
s
= – kx
, where k is the spring constant.
How do you find the period of an object?
So
r = d/2
. Note also the symbol for the period: T. With this equation, given an orbiting object’s speed and the radius of the circle, you can calculate the object’s period. Another measurement you’ll see in physics problems is frequency.
How do you calculate the period of a pendulum?
- Determine the length of the pendulum. …
- Decide a value for the acceleration of gravity. …
- Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s .
- Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz .
How do you find the spring constant given the mass and period?
The period of a mass m on a spring of spring constant k can be calculated as
T=2π√mk T = 2 π m k
.
What is spring constant measured in?
The rate or spring constant, k, relates the force to the extension in SI units:
N/m or kg/s2
.
Does period affect mass?
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 is the period of circular motion?
The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression
2•pi•R / T
. Often times the problem statement provides the rotational frequency in revolutions per minute or revolutions per second.
What is the formula of circular motion?
| Equation Symbol breakdown | v = r ω v = r omega v=rω v v v is linear speed, r is radius, ω is angular speed. | T = 2 π ω = 1 f T = dfrac{2pi}{omega} = dfrac{1}{f} T=ω2π=f1 T T T is period, ω is angular speed, and f is frequency |

What is the period of a 1’m long pendulum?
The period of a 1 meter long pendulum is
2 seconds
. The amplitude is the maximum displacement of the bob from its equilibrium position. When the pendulum is at rest, not swinging, it hangs straight down.
What does period of pendulum depend on?
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.
What is frequency of a pendulum?
Thus, the frequency of the pendulum defines
how many times the pendulum moves back and forth in a specific period of time
. For example, how many times the pendulum moves back and forth in 60 seconds. The frequency of the pendulum is determined by its length. It means shorter the pendulum, the swing rate will be more.
Does the spring constant have a unit?
The defining character of a spring is that it resists displacement from its rest position with a force which increases linearly: restoring force
Does the spring constant change with mass?
| Mass (kg) Force on Spring (N) Amount of Stretch (m) | 0.400 3.920 0.0160 | 0.500 4.900 0.0199 |
|---|
How does mass affect period of a spring?
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.
