Question 28
The diagram shows the relative strengths of gravitational force for planets of different masses. The size of each planet represents its relative mass. The arrow length indicates the relative amount of gravitational pull that each planet would exert on an astronaut in space.
Key: arrow length = relative gravitational pull; planet size = relative mass.
What is the relationship between the mass of the planets and the relative strength of their gravitational pull?
Key: arrow length = relative gravitational pull; planet size = relative mass.
