The potential energy is converted into kinetic energy.
For the projectile's speed, the expression can be solved.
The numbers seem reasonable.
The force needed to compress the spring is small enough for an adult to manage, and the energy given to the dart is small enough to limit the damage it can do.
The dart is able to travel an acceptable distance because of its speed.
Imagine holding the end of a ruler with one hand and then using the other to change it.
You can see the ruler's movement when you let go.
You could hold the ruler at its center so that the part of the ruler that is moving is half as long as the original experiment.
Potential energy was stored in the object.
The sound of a guitar string has a steady tone and lasts a long time.
The string takes the same amount of time each time.
It may be any convenient unit of time.
The term period refers to the time for some event whether repetitive or not, but we will be interested in periodic motion, which is repetitive.
Frequency of an event is a concept closely related to period.
The period between checks is half a month if you get a paycheck twice a month.
Frequency is the number of oscillations per unit time.
One complete oscillation is a cycle.
A single or multiple event can be a vibration, whereas a repetitive event can be a oscillations.
We can use the formulas presented in this module to determine the frequencies based on the known frequencies.
Let's see if we can come up with an example of each.
The relationship between period and Frequency can be used to answer both questions.
The period is given and we are asked to find frequencies.
We are asked to find the period when the Frequency is given.
The highest level of sound that humans can hear is called the highest level of sound that humans can hear is called the highest level of sound that humans can hear is called the highest level of sound that humans can hear is called the highest level of sound that humans can hear is called the highest level Fetal observations in the womb and other non-destructive medical diagnoses can be made using appropriate frequencies.
