- Why doesn’t a spacecraft in orbit fly off into space? Why doesn’t it hit the ground?
- How is this similar to the Earth in orbit around the Sun?
Homework Answers
The spacecrafts in the Orbit around the Earth are controlled by the Gravitational pull of the Earth. This force pulls the spacecrafts towards earth, known as Centripetal Force.
On theother hand the spacecrafts also move in orbit with some determined speed. This speed, causes and outward force on spacecrafts, named as Centrifugal Force.
Now the speed of the Spacecrafts is set in such away that the Centrifugal and Centripetal forces balance each other. So neighter a spacecraft can fall back on Earth, nor can it fly off into space. That's why it stays in its orbit without failing.
Same relationship of Gravity and speed is between Earth and Sun, with Sun's Centripetal Gravitational force, and Earth's speed as Centrifugal Force balancing each other.

(1s equal to pt) A s spacecraft of mass m is in a circular orbit around the Sun with the radius R average Earth-Sun distance. At point A, the spacecraft is firing its thrusters Sun, to point E the tangentially to the closer to the s e trajectory such that it will fall on an elliptical orbit, which will bring it un, to point B. At point B, it once again fires its thrusters tangentially to its ry to go...

Consider a very small spacecraft in a circular orbit around the earth. Suppose it is in this orbit for some time, but then, instantaneously, the Earths mass suddenly becomes 50% smaller than it was previously. Determine the resulting orbit of the spacecraft and justify your answer. (note: assume that the only effect on the spacecraft is that it is subsequently moving in the gravitational field of a 50% less massive Earth, and its mass and velocity are the same just...

23. A spacecraft is in orbit around the Earth, where if feels a gravitational force of magnitude F. At that moment, it is located a distance L away from the center of the Earth. Later, the spacecraft leaves orbit and travels away from the Earth to visit an asteroid which is passing by. When it reaches the asteroid, it is a distance 40L away from the center of the Earth. What is the force of gravity on the spacecraft from...

The Solar and Heliospheric Observatory (SOHO) spacecraft has a special orbit, located between the Earth and the Sun along the line joining them, and it is always close enough to the Earth to transmit data easily. Both objects exert gravitational forces on the observatory. It moves around the Sun in a near-circular orbit that is smaller than the Earth's circular orbit. Its period, however, is not less than 1 yr but just equal to 1 yr. Show that its distance...

A minimum-energy transfer orbit to an outer planet consists of putting a spacecraft on an elliptical trajectory with the departure planet corresponding to the perihelion of the ellipse, or the closest point to the Sun, and the arrival planet at the aphelion, or the farthest point from the Sun. (Assume the orbital radius of the Earth is 1.50 times 10^11 m, and the orbital radius of Mars is 2.28 times 10^11 m.) Use Kepler's third law to calculate how long...

A spacecraft with mass 1500 kg is in a circular orbit at an altitude 200 km above the surface of Earth. A) Use the Law of Universal Gravitation and Newton's 2nd law for circular motion to derive and find the speed of the spacecraft in this orbit. B) How much mechanical energy does the spacecraft have in this orbit? C) How much work must the spacecraft engines perform to get it into the above circular orbit from the surface of...

An unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 55.0km . To the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 15 m/s. If nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface? .
