What is a dynamic force?
In physics, dynamic force can be closely described as the amount of acceleration/velocity, usually in uniform circular rotation, needed to move an object.
How does the atmasphere help earth?
Our atmosphere helps in a number of ways: 1. It filters out harmful UV rays from the sun that would burn all living things. 2. It creates a blanket that keeps the temperature relatively stable. 3. The atmosphere provides oxygen needed to sustain animal life and carbon dioxide needed to sustain plant life. 4. It provides a mechanism for water to move from the oceans to land - allowing plants and animals to live on land. 5.it makes you feel sooooooooooooo much cuter
What does a charcoal canister do on a vehicle?
It captures fuel vapors and prevents them from escaping to the atmosphere and then stores the fumes and recycles them to the fuel tank or engine intake for combustion as needed. The long and short of it is that it helps to protect the environment and improve fuel economy.
Why There is no work done when satellite rotate around earth?
With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.

Why is the atmosphere needed on a planet?
Atmospheres have many different purposes, however the Earths atmosphere is vital to its existense as it prevents the suns harmful radiation from reaching the Earths surface. Moreover, from an enviromental standpoint the errosion by pollutants will eventually destroy the delicate atmosphere and the Earths protective barrier will be gone.
Why do all plants and animals depend on earths atmosphere?
Plants and animals depend on Earth's atmosphere for essential gases like oxygen and carbon dioxide. Oxygen is required for respiration in animals, while carbon dioxide is needed for photosynthesis in plants. The atmosphere also provides protection from harmful solar radiation and regulates the temperature of the planet, creating a stable environment for life to thrive.
What gas was needed to be established within the earths atmosphere before the atmosphere was able to absorb and maintain heat?
The gas needed to establish before the Earth's atmosphere could absorb and maintain heat was carbon dioxide. This gas, along with other greenhouse gases like methane and water vapor, trap heat in the atmosphere and help regulate the Earth's temperature.
What is the speed needed to enter the earths atmosphere?
It is difficult to answer this question because it mainly depends on the size and mass of an object. Most space debris sizes, almost like a land-rover, need hypersonic speed to enter the earth's atmosphere. This speed is classified as Mach 5 and over. (Mach means traveling at speed of sound, which means moving about one mile in five seconds) Meteors enter at a different rate. Most meteor-sized objects penetrate the earth's surface at roughly 30 miles an hour or a little more. Other things, like shuttles, need speeds a little more than the speed of sound. Because of their mass and size, more thrust is needed to penetrate the earth's atmosphere.
Why do rockets and spaceshuttles break up when travelling in space?
The only reason for the rocket is to fire the shuttle out of the earths atmosphere, once in space the rocket is no longer needed and there for they detach.
Which element in earths atmosphere is essential for human life?
Oxygen is the most essential element in Earth's atmosphere for human life. It is needed for cellular respiration, the process by which our cells generate energy. Without oxygen, humans would not be able to survive.
Why are map projecters needed?
to draw the earths surface.
Why is the Earths atmosphere needed for life?
The Earth's atmosphere is necessary for life because it contains oxygen for respiration, regulates temperature, protects against harmful rays from the sun, and provides the air we breathe. Without the atmosphere, conditions on Earth would be too extreme for life to exist.
Can sperm penetrate clothing and result in pregnancy?
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?
The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.
Why is Jupiter the hardest planet to take off from if your in a spaceship?
Jupiter's strong gravity and immense size make it difficult for a spaceship to achieve escape velocity needed to overcome its gravitational pull. Additionally, Jupiter's thick atmosphere creates drag that further hinders spacecraft from leaving its orbit.
How do rockets get out of the atmosphere?
Basically, A extreme amount of thrust must be first produced for the rocket to reach the excessive hight needed. Once it's reached the speed needed it can easily breach the Earths Ozone layer.
