Title: What is the acceleration due to gravity on the surface of this planet? Post by: smokeypal23 on Jan 1, 2013 A planet X has a mass that is half the mass of the earth, and a radius that is half the radius of the earth. What is the acceleration due to gravity on the surface of this planet in m/s^2?
Please also explain how to solve this problem. Title: What is the acceleration due to gravity on the surface of this planet? Post by: tony960831 on Jan 1, 2013 Force goes up directly with the mass of the planet and down with the inverse square of the radius. So, the mass would multiply by .5 and the radius would divide by .5^2.
.5/(.5^2) = 2 times the earths gravity so earths acceleration is 9.8 so this is 19.6 |
