It takes greater force to accelerate an object that has more mass. But the gravitational force between the Earth and an object is greater when the object hass more mass. It works out just right to make any object with any mass accelerate at the same rate.
Gravitational acceleration is the same for all objects near Earth, approximately 9.8 m / s 2 , regardless of their mass. This is due to the fact that while heavier objects experience greater gravitational force, they also have greater inertia, resulting in the same rate of acceleration. Galileo's experiments historically confirmed this concept by showing that different masses fall at the same rate when air resistance is negligible.

Penjelasan dengan langkah-langkah:Pusat (-2, 3), r = 5(x - (-2))² + (y - 3)² = 5²x² + 4x + 4 + y² - 6y + 9 = 25x² + y² + 4x - 6y + 4 + 9 - 25 = 0x² + y² + 4x - 6y - 12 = 0Jadi, persamaan lingkaran tersebut adalah x² + y² + 4x - 6y - 12 = 0
