How fast must an object travel in order to orbit the Earth?

The speed required for an object to go into space and orbit the Earth (orbital velocity) is about 28,000 km/hr (17,500 mph) at low earth orbit. At this speed the object will be able to go into space and maintain a constant orbit around the Earth at an altitude of around 325 km (200 km).

How fast would an object have to lock into low Earth orbit?

Satellites that orbit very close (including, for example, the International Space Station, around 400 kilometers, or 250 miles, from the surface) must streak around the planet at about 7.7 kilometers per second (17,000 mph) to keep from being pulled down.

What takes 90 minutes to orbit the Earth?

The ISS
The ISS weighs almost 400 tons. It’s about as wide as an American football field. It travels at 17,500 mph and can orbit the Earth every 90 minutes.

Does a satellite closer to Earth must travel faster to maintain its orbit?

The nearer to Earth, the faster the required orbital velocity. To maintain an orbit that is 22,223 miles (35,786 kilometers) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph).

How fast does a satellite have to travel to stay in orbit?

about 7,000 mph
To maintain an orbit that is 22,223 miles (35,786 km) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). That orbital speed and distance permits the satellite to make one revolution in 24 hours.

How fast is reentry speed?

17,500 mph
As a spacecraft re-enters the earth’s atmosphere, it is traveling very much faster than the speed of sound. The aircraft is said to be hypersonic. Typical low earth orbit re-entry speeds are near 17,500 mph and the Mach number M is nearly twenty five, M < 25.

How fast do you need to orbit?

A spacecraft leaving the surface of Earth, for example, needs to be going about 11 kilometers (7 miles) per second, or over 40,000 kilometers per hour (25,000 miles per hour), to enter orbit. Achieving escape velocity is one of the biggest challenges facing space travel.

How fast does the earth rotate?

roughly 1,000 miles per hour
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.

How fast do satellites travel per second?

Most satellites are launched into low Earth orbit, since this requires the minimum launch energy. At the orbital speed of 8 kilometers per second, they circle the planet in about 90 minutes.

What happens to an object moving without opposing friction?

According to Galileo, an object moving without opposing friction or other opposing forces will. a. still need a constant force to keep it moving at a constant speed. b. need an increasing force, or it will naturally slow and then come to a complete stop. c. continue moving at a constant speed.

What is the rate of acceleration when you drop an object?

If you drop an object, it will accelerate downwards at a rate of 9.8 m/s2. If you instead throw it downwards as hard as you can, its acceleration after it leaves your hand will be _____ to 9.8 m/s2

What did Galileo say about the distance of a falling object?

Galileo reasoned that the distance a freely falling object is proportional to the square. True If a 16 lb bowling ball and a 10 lb bowling ball are dropped from the 5th floor at the same time the heavier ball will reach the ground first. False

What happens when a heavy object and a light object are dropped?

A heavy object and a light object are dropped from rest at the same time in a vacuum. The heavier object will reach the ground A. before the lighter object B. at the same time as the lighter object C. after the lighter object D. it depends on the shape of the object
