How is the formula for period of oscillation derived?

In summary, the formula for period of oscillation is T = 2π√(m/k), where T is the period, m is the mass, and k is the spring constant. It is derived using Hooke's Law and Newton's Second Law of Motion, which state that the force exerted by a spring is directly proportional to the displacement from its equilibrium position and that the force exerted on an object is equal to its mass multiplied by its acceleration. This formula can be applied to all types of oscillating systems as long as they follow these laws. The period of oscillation is affected by the mass, spring constant, and amplitude of the oscillation, with increasing mass or spring constant resulting in a longer period, and

In sprind
F = -kx
ma = -kx
a - -(k/m)x
d^2x/dt^2 = -(k/m)x

Put x = Asin(ωt)
And substitute in the above equation.

Take an undamped spring-mass system (spring constant k, mass attached m), write down Newton's 2nd Law, and see where it leads.

(A bit late, pardon me)
 

1. What is the formula for period of oscillation?

The formula for period of oscillation is T = 2π√(m/k), where T is the period, m is the mass, and k is the spring constant.

2. How is the formula for period of oscillation derived?

The formula for period of oscillation is derived using Hooke's Law and Newton's Second Law of Motion. Hooke's Law states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position. Newton's Second Law states that the force exerted on an object is equal to its mass multiplied by its acceleration. By combining these two laws, we can derive the formula for period of oscillation.

3. Can the formula for period of oscillation be applied to all types of oscillating systems?

Yes, the formula for period of oscillation can be applied to all types of oscillating systems, as long as they follow Hooke's Law and Newton's Second Law of Motion.

4. What factors affect the period of oscillation?

The period of oscillation is affected by the mass of the object, the spring constant, and the amplitude of the oscillation. Increasing the mass or the spring constant will result in a longer period, while increasing the amplitude will result in a shorter period.

5. How does the formula for period of oscillation relate to the concept of frequency?

The frequency of an oscillating system is the number of oscillations it makes per unit time. It is the inverse of the period, meaning that as the period increases, the frequency decreases, and vice versa. Therefore, the formula for period of oscillation can also be written as T = 1/f, where f is the frequency.
