Acceleration Due to Gravity Video Lessons

Concept

# Problem: The value of g at the height of the Space Shuttle’s orbit is:A. 9.8 m/s2.B. slightly less than 9.8 m/s2.C. much less than 9.8 m/s2.D. exactly zero.

###### FREE Expert Solution

Gravity at height:

$\overline{){\mathbf{g}}{\mathbf{=}}{\mathbf{g}}\frac{{\mathbf{R}}^{\mathbf{2}}}{{\mathbf{\left(}\mathbf{R}\mathbf{+}\mathbf{h}\mathbf{\right)}}^{\mathbf{2}}}}$

g decreases with the increase in height above sea level.

According to NASA, the radius of the orbit ranges between 304 km to 528 km
