Question

Newton’s first law says that a body will remain in a state of rest, or move in a straight line at a constant speed, unless it is acted upon by an outside force. What is acting upon the Hubble Space Telescope (HST) to keep it in the curved path of its orbit around the Earth?

Answer 1

Answer:

Gravity

Explanation:

The Hubble is continually attracted to the earth due to the action of gravity. Therefore, it is thanks to gravity that the space telescope is kept in orbit. Without him, the direct motion generated by inertia would take him out of course. Gravity slows it down and keeps it in the curved path of its orbit around the Earth.
