gimme a side of what physical science is. I know there's no shortcuts but it means alot of ev'rything I gotta know. Sho' me.
I have little understanding of what you wrote. When one tries to communicate in non-standard English, the results are unpredictable.
Here is a definition of physical science:
physical science
(noun) : any of the natural sciences (as physics, chemistry, and astronomy) that deal primarily with nonliving materials

Echoes are the reflection of sound waves off a surface. They occur when sound waves bounce off a solid object and return back to the source. To create an echo, you need a sound source, an obstruction or reflecting surface, and an open space for the sound to travel.
To create an echo, follow these steps:
1. Find a suitable location: Choose a place with enough open space for the sound waves to travel without obstruction.
2. Make a loud sound: Clap your hands, shout, or use any other loud sound source. The sound waves will travel through the air.
3. Listen for the echo: After making the sound, wait for a few seconds for the sound waves to bounce off a solid surface, such as a wall or a mountain, and return to your location. You will hear a repeated, fainter sound, which is the echo.
4. Measure the time delay: If you want to calculate the distance to the reflecting surface, you can measure the time between making the sound and hearing the echo. Multiply that time by the speed of sound in air (approximately 343 meters per second) to calculate the distance traveled.
It's important to note that the quality of an echo depends on the environment, the distance to the reflecting surface, and the type of sound source.
