What happens when a satellite loses energy?

So the drag from the air slows the satellite down, the satellite loses energy and the size of the orbit gets smaller and smaller until it gets into a part of the air where friction builds up so much that the satellite just burns up.

What would happen to a satellite in orbit if it suddenly stopped?

There would be no more satellite data showing the health of crops, illegal logging in the Amazon or Arctic ice cover. Satellites used to produce images and maps for rescue workers responding to disasters would be missed, as would the satellites producing long-term records of climate.

What is the trajectory of a satellite?

2.1 Definition of an Orbit and a Trajectory While a trajectory is a path traced by a moving body, an orbit is a trajectory that is periodically repeated. While the path followed by the motion of an artificial satellite around Earth is an orbit, the path followed by a launch vehicle is called the launch trajectory.

Is a satellite loses some of its total energy then?

If the satellite loses some energy, its total energy will decrease.

How does speed affect orbiting altitude?

The higher the orbit (larger distance between the planet and the satellite), the less speed is required to prevent the satellite from falling out of its orbit and crashing into the planet. The nearer the orbit, the faster it must move to ensure that it does not crash into the planet.

What happens if the Earth stops orbiting?

First off, if Earth stopped short, you’d actually die immediately because you’d fly off the planet and hurtle into space, just like you lurch forward in a car when a driver slams on the brakes. But if Earth slows down more gradually, you’d instead suffer a slower (but still horrific) death.

What happens if the Earth stops orbiting the sun?

If the Sun were to suddenly disappear, Earth would travel in a perfectly straight line at 30 km/s. In other words, anything on the Earth’s leading side would fly off into space, continuing along the Earth’s orbital path around the Sun. Anything on the trailing side would be pulverized against the Earth.

Is an orbit a trajectory?

In celestial mechanics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory.
