## What is the equation for pendulum motion?

By applying Newton’s secont law for rotational systems, the equation of motion for the pendulum may be obtained τ=Iα⇒−mgsinθL=mL2d2θdt2 τ = I α ⇒ − m g sin θ L = m L 2 d 2 θ d t 2 and rearranged as d2θdt2+gLsinθ=0 d 2 θ d t 2 + g L sin If the amplitude of angular displacement is small enough, so the small angle …

**What was the role of Christiaan Huygens in the establishment of the pendulum law?**

His interest, as an astronomer, in the accurate measurement of time then led him to his discovery of the pendulum as a regulator of clocks, as described in his Horologium (1658).

### What is the formula of velocity in simple pendulum?

The velocity of the mass on a spring, oscillating in SHM, can be found by taking the derivative of the position equation: v ( t ) = d x d t = d d t ( A cos ( ω t + ϕ ) ) = − A ω sin ( ω t + ω ) = − v max sin ( ω t + ϕ ) .

**What did Galileo discover about pendulums?**

Galileo’s discovery was that the period of swing of a pendulum is independent of its amplitude–the arc of the swing–the isochronism of the pendulum. [1] Now this discovery had important implications for the measurement of time intervals.

## Who derived the pendulum equation?

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. The Italian scientist Galileo first noted (c.

**What is pendulum motion?**

The type of motion associated with the pendulum is called periodic motion or we can say it as oscillation. The bob of the pendulum moves back and forth and creates an oscillation motion.

Christiaan Huygens/Discovered

Christiaan Huygens was a mathematician, physicist and astronomer who formulated the wave theory of light. He also discovered the pendulum clock, centrifugal force and the true shape of the rings of Saturn (as well as its moon, Titan).

## Who discovered the pendulum equation?

Christiaan Huygens

Such was the case with 17th century Dutch astronomer Christiaan Huygens. He became the first to report the phenomenon of coupled oscillation in two pendulum clocks (which he invented) in his bedroom while recovering from an illness in 1665.

**What is pendulum theory?**

The Pendulum Theory is the concept that there are three basic philosophical positions Western societies occupy. Societies swing from one position to the other like the pendulum in a grandfather clock.
