Explanation

• In a vacuum, both balls reach the ground at the same time because there is no air resistance.
• All objects fall with the same gravitational acceleration (9.8 m/s²).
• The mass of an object does not affect its falling speed in a vacuum.
• This principle was demonstrated by Galileo Galilei.
