Why do model solar systems need two scales?

Distances are so large compared with planet sizes that one scale cannot show both. The sheet uses 1 AU = 10 cm for distance and 1 cm = 10,000 km for size.

What happens to gravity if distance doubles?

The force falls to one fourth. If one mass doubles, the force doubles.

Written by Adi Ackerman, Head Teacher

The solar system is the Sun and the planets and other objects held in orbit by gravity. There are 2 sheets for 7th grade here, each with an answer key. Graph How Distance Weakens Gravity completes tables of relative force and applies the rules to satellites, and Build a Scale Model of the Solar System converts distances in AU and diameters in km to centimeters. The sheets practice MS-PS2-4 and MS-ESS1-3.
