Question

Think of the term that fits into or defines the given statement and fill in the given boxes with the correct spellings of that term.

The gravitational pull of the earth does not _________ on a satellite circling around the earth.

Answer 1

1. The force of gravity is always perpendicular to the path of the motion of the satellite circling around the earth.
2. Since the angle between the force and displacement is perpendicular, the work done is zero.
3. $$\begin{gathered} Workdone=Force\times Displacement\times Anglebetweenthem \\ W=FS\cos \theta \\ Here\cos \theta =0thereforeW=0 \end{gathered}$$

Hence, the gravitational pull of the earth does not work on a satellite circling around the earth.
