Question

An artificial weather forecasting satellite is revolving around the earth.
(i) What is the direction of motion of the satellite at any instant
of time?
(ii) Is the motion accelerated? Justify your answer.

Answer 1

Answer:

The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth's radius plus the height above the earth - in this case, 6.77 x 106 m. Substituting and solving yields a speed of 7676 m/s.

A satellite orbits Earth when its speed is balanced by the pull of Earth's gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. ... It moves in the same direction and at the same rate Earth is spinning.
