# Simple Pendulum Calculator English Español

A pendulum is a mass that is attached to a pivot, from which it can swing freely. Simple Pendulum is a mass (or bob) on the end of a massless string, which when initially displaced, will swing back and forth under the influence of gravity over its central (lowest) point. Use this online simple pendulum calculator to calculate period, length and acceleration of gravity alternatively with the other known values. Enter the given values and click calculate.

### Example

#### Acceleration of Gravity(g)

Find the Acceleration of Gravity(g) when the length of the string is 2m and the Pendulum oscilation time 23s.

g = (4 * π2 * L) / T2
g = (4 * π2 * 2) / 232
g = 0.15 m/s2

#### Length(L)

Find the Length(L) when the Acceleration of Gravity(g) is 9.8 m/s2 and the Pendulum oscilation time 23s.

L = (T2 * g) / (4π2)
L = (232 * 9.8) / (4π2)
L = 131.45 m

#### Period(T)

Find the Period(T) when the Acceleration of Gravity(g) is 9.8 m/s2 and length of the string is 2m.

T = 2π √(L/g)
T = 2π √(2 / 9.8)
T = 2.84 s
