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.
What is the objectives of power quality?
The main objective would be reliable, dependable power when needed, were needed.
Why is the Earths atmosphere needed for life?
because it keeps the air inside the earth
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.
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.
Why are map projecters needed?
to draw the earths surface.
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
How much thrust is needed to escape earths gravity if something weighs 1520 pounds?
The general idea is that the escape velocity from Earth is 11.2 km/second. This assumes there is no atmosphere. I guess "thrust" would be expressed in units of force; the force can be just about anything, from just slightly bit more than the object's weight (to counter Earth's gravity), to a lot more, depending how long the force is applied. In other words, if you apply more force, you need to apply the force for less time to achieve escape velocity.
What must be included when reporting an objects velocity-?
Speed and direction of motion are needed to determine velocity.
What is oxyghen?
An incorrect spelling of the word oxygen, which is an element found in many organic compounds. O2 is the chemical formula for oxygen found as a gas and is about 21% of the earths atmosphere, which is needed for aerobic respiration and therefore to sustain life.
What is the velocity needed for atom boom formula?
speed of light
What are needed to completely describe velocity?
Speed and direction of motion.
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?
?Initial velocity?
