Here's why:
* Acceleration due to gravity (g): This is the rate at which objects accelerate towards the Earth. It's roughly 9.8 m/s², meaning that for every second an object falls, its speed increases by 9.8 meters per second. This value is constant for all objects near the Earth's surface, regardless of their mass.
* Force of gravity (Fg): This is the actual force exerted by the Earth on an object. It depends on the object's mass and the acceleration due to gravity. The formula is:
Fg = m * g
where:
* Fg is the force of gravity
* m is the mass of the object
* g is the acceleration due to gravity
Therefore, a heavier object will experience a greater force of gravity than a lighter object, even though they both accelerate at the same rate.
Example:
* A feather and a bowling ball both fall at the same rate (acceleration due to gravity is the same).
* However, the bowling ball, being much heavier, experiences a much stronger force of gravity than the feather.
Important Note: This is a simplified explanation. The acceleration due to gravity is not *exactly* constant across the Earth's surface due to factors like the Earth's shape and local variations in density. However, the differences are small enough that for most practical purposes, we can consider g to be constant.
