Air restistance causes friction against a moving object and can cause it to slow down. For example a parachutes job is to makes air restistance to slow down whatever it is trying to stop from falling. the parachute is there to even out the air restistance with the force gravity.
What else can I help you with?
Is there such thing as hot air and cold air?
Yes, there is hot air and cold air. Hot air is air that has been heated and has a higher temperature, while cold air is air that has a lower temperature. Temperature differences in the air can affect weather patterns and create variations in temperature in different regions.
Which occurs when air is compressed A. Air Temp rises and air molecules move faster B. Air temp decreases C. Air temp decreases and air molecules move faster D. Air molecules move slower?
A. air temperature rises and air molecules move faster
What effect does cold air have on air pressure?
Cold air is denser than warm air, so it exerts a higher pressure. When cold air moves into an area, it can increase the air pressure in that location. Conversely, when warm air moves into an area, it can decrease the air pressure.
What is the push of air called?
The pushing force of air is called air pressure.:)
What do air density and air pressure have in common?
Air density and air pressure are both properties of the atmosphere that are related to each other. As air density increases, air molecules are packed more closely together, which also leads to an increase in air pressure. Conversely, as air density decreases, air pressure decreases as well.
What is air reistance?
kings school Winchester 9.2.1 science period 2.
Is air reistance a contact force?
Yes, air resistance is a contact force. It is caused by the overall force created when thousands of tiny air particles collide with your body (or a parachute etc). All of the tiny collisions add up to the larger force you feel as air resistance
What are photoconductive cells?
The photoconductive cell is a two terminal semiconductor device whose terminal reistance varies linearly with the intensity of incident light .
How the Jews were freed from Buchenwald?
The Jews along with other minorities were freed from Buchanwald when it was liberated. It was liberated onon April 11th 1945 during the Buchenwald reistance.
Do gold plated cables operate more efficiently?
Silver doesn't last as long and provides a reistance reducing quality signals.. So yes Gold is better all around.
What does an avo meter do?
An AVO meter is used for electrical measurements, it's name comes from it's ability to measure Amps, Volts and Reistance. Generally considered the best analogue multimeter ever made.
How do you check if a diode is serviceable?
use a vomm set to infinite resistance if you have reistance one way and not the other way. diode is good (must be isolated from circuit) if no resistance both directions diode D.O.A.
Why is stitching on a baseball important?
There are 108 double stiches in an official baseball. They are carefully stiched in a pattern that goes from wide to narrow because this effects aerodynamics. When the air passes over the ball the stiches help produce a more streamlined effect which reduces the amount of drag on the ball-Drag is the reistance an object faces when it collides with air molecules, it is a type of friction which can slow down the ball.
Why were the Marathon and the Thermopylae important to the Persian War?
They were rallying calls for the Greeks. The Athenian success at Marathon demonstrated to the other Greek cities that the Persians could be beaten. Thermopylae became another symbol for Greek steadfastness which was used by the Greeks for propaganda on the superiority of the Greek warrior.
Can I put air in my air bags?
You can put Air in Air Shocks Not Air Bags
