You're right, objects with larger mass experience a stronger gravitational pull. But the question is: what do they *have* more of?

The answer is inertia.

Here's why:

* Gravity: Gravity is a force that attracts objects with mass towards each other. The more massive an object, the stronger its gravitational pull.

* Inertia: Inertia is the tendency of an object to resist changes in its motion. The more massive an object, the harder it is to get it moving or to stop it once it's moving.

So, while gravity pulls more strongly on more massive objects, their increased inertia makes them harder to accelerate. It's like pushing a car versus pushing a bicycle - the car has more mass, so it requires more force to get it moving.
