16.5 Energy and the Simple Harmonic Oscillator
The method for determining can be very accurate.
This is the reason for the length and period to be five digits.
The maximum displacement angle should be kept below, so that the approximation is better than the pendulum length and period.
Knowing can be important in geological exploration, for example, a map of large geographical regions can be used to find oil fields and large mineral deposits.
The movement of the pendula will not change because of the mass of the bob.
The pendula are only affected by the period and the acceleration due to gravity.
The period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing.
The photogate timer can be used to measure the period.
The strength of gravity can be varied.
The pendulum can be used to find the value of planet X.
The other important form of energy is kinetic energy.
In the case of undamped simple motion, the energy goes from one to the other as the system changes.
The elastic potential energy is converted to kinetic energy as the object moves.
When the elastic potential energy is converted back into elastic potential energy by the spring, the velocity becomes zero.
Extra insight can be provided by this concept in applications such as alternating current circuits.
An object attached to a spring is shown to have a transformation of energy.
The expression for velocity can be derived from the conserved energy principle.
The total energy is constant and is shifted back and forth between the two.
The expression shows that the velocity is a maximum at.
The maximum speed depends on three factors.
The maximum speed is proportional to the amplitude.
The greater the maximum displacement, the greater the maximum speed.
Striking systems exert greater force for the same displacement.
The expression shows that this observation is proportional to the square root of the force constant.
The maximum velocity is smaller for larger objects because it is proportional to the square root.
Large objects accelerate more slowly than smaller ones.
A car with a suspension system that has a force constant is 900 kilograms.
The maximum vertical velocity can be determined using the expression for given in.
The maximum displacement is 0.100 m and the variables are given in the problem statement.
It's possible to identify known.
The answer seems reasonable for a bouncing car.
There are other ways to conserve energy.
In the example featured in Hooke's Law: Stress and Strain Revisited, we could use it directly.
