INERTIA.

Massive things have more mass (duh!), more gravitational force, and more inertia. If you think that car was hard to move with a flick of your fingers, just imagine how tough it would be for the apple’s gravitational field to yank the Earth up to it. Not gonna happen!

One more question:

Is the acceleration of the apple dropping to the Earth

• greater than
• less than
• about the same as

the acceleration of the Earth up to the apple?

Greater than, of course! You can definitely observe that.
