A pendulum consists of a 1.5kg mass swinging at the end of a string of length 2.0m. At the lowest point in the swing the tension in the string is equal to 20N. To what maximum height above this lowest point will the mass rise during its oscillation?
Homework Equations
I'm not sure.
The Attempt at a Solution
Idk where to start.
A pendulum is a weight suspended from a fixed point that can swing freely back and forth under the influence of gravity.
The period of a pendulum is affected by the length of the pendulum, the weight of the pendulum's bob, and the acceleration due to gravity.
A pendulum demonstrates simple harmonic motion because its motion is periodic and can be described by a sine or cosine function. The restoring force of gravity causes the pendulum to oscillate back and forth in a regular pattern.
The length and period of a pendulum have an inverse relationship. This means that as the length of the pendulum increases, the period also increases, and vice versa. This relationship is described by the formula T = 2π√(L/g), where T is the period, L is the length, and g is the acceleration due to gravity.
The amplitude (maximum displacement from the equilibrium position) of a pendulum does not affect its period. The period of a pendulum is only dependent on the length, weight, and acceleration due to gravity. However, larger amplitudes may cause the pendulum to lose energy faster due to air resistance, resulting in a slightly shorter period.
