Brett and rachel learn the iss is a very large
spacecraft with a mass of about 400,000 kilograms
(kg).
brett thinks earth would exert the same
gravitational force on a less massive spacecraft as it
does on the iss. rachel thinks the gravitational
force would be different because an object's weight
on earth depends on its mass and gravity.
brett and rachel investigate how gravitational
forces in newtons (n) affect objects of different
masses in kilograms using a simulption.
select a mass from the menus for objects 1 and 2.
then, click run to watch the simulation.
next, run at least three more trials with varying
masses for both objects.
