When a parachutist is falling with his parachute open, he is hitting air molecules. Imagine he is going at 1 cm/s, he is hitting 1 cubic cm of air molecules per second. If he goes at 2 cm/s, then he is hitting 2 cubic cm of air per second. This increases the air resistance. So as his speed increases, so does the amount of cubic cm of air molecules.
What else can I help you with?
What objects cause air particles?
Objects such as fans, airplane wings, and moving vehicles can cause air particles to move by creating disturbances or pressure differences in the air. These disturbances result in the displacement and movement of air particles.
What problems do particles in the air cause?
carbon dioxide and unhealthy air
What direction does air particles move when they cause vibration?
Air particles move back and forth in the direction of the vibration when they cause it. The energy from the vibrations is transferred through the air as sound waves.
What has more energy particles in cold water or in the air?
air is has more particles cause it covers all the earth vs the particles in cold water
Are movement of gas particles in the air against another object cause air pressure?
No
Is gas particles in the air pressure?
Gas particles in the air contribute to air pressure. The molecules constantly collide with each other and with surfaces, exerting a force per unit area, which we perceive as pressure. The more gas particles present in a given space, the higher the air pressure will be.
How does air pressure move air particles?
Air pressure is the force exerted by the weight of air in the atmosphere. Differences in air pressure cause air particles to move from areas of high pressure to areas of low pressure, in an attempt to equalize the pressure. This movement of air particles creates wind.
How do ions remove dust pollen another foreign particles from the air?
The cause is the electrostatic attraction between ions and these particles.
Removing heat from the air will the air temperature?
Removing heat from the air will decrease the air temperature. Heat is what gives particles in the air energy to move and the removal of heat will cause the particles to slow down, resulting in a decrease in temperature.
Indoor polution sources that release gases or particles into the air are the primary cause of indoor airquality problems in homes and businesses?
indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes and businesses?
What is caused be gravity acting on suspended particles in the air?
Gravity acting on suspended particles in the air can cause them to fall to the ground, leading to phenomena like rain or snow.
What is it called when particles in air get squished together as the wave passes by?
This is known as compression. Sound waves cause air particles to compress and move closer together as they pass through.
