5. What is the unit of measurement for force? _____________________________
** Scroll down to the Procedure Section. Carefully read the instructions!
Directions: Choose planets o different masses and gravities and objects of different
masses and gravities to investigate. Drop the objects and record your results below.
Be sure to pay carefully attention to what you are noticing about the size of mass
and the gravity of the plant in relation to how fast the objects fall.
