• In a vacuum, when an object falls it is subjected to only one kind of force, that is, the gravitational force, which is considered as the object's weight.
• In a vacuum, all the objects fall at the same rate due to gravitational force. In a vacuum, the mass of the object does not matter.
• In a vacuum, the moving of the object only takes place due to gravity is considered to be free-falling, and its motion is illustrated by Newton's second law of motion.
Thus, gravitational force does exist in a vacuum.
To know more about:
Answer: False
