That's called the "force of imagination".
In the absence of air, all objects fall with the same acceleration. At equal times after the drop, all objects
are falling at the same speed.
action (versus reaction, the opposing force to action). ================
Gravity.
fricion
inertia
force is something that makes objects change velocity.

Gravity.
fricion
A force called "gravity" makes that any mass attract any other mass. The larger the masses, the stronger will the force be. The greater the distance, the smaller will this force be.
That substance is called a lubricant. An example would be oil.
attraction
gravitational, electrostatic, and magnetic forces
inertia
force is something that makes objects change velocity.
Outward force that makes objects move in a circle, then make them fly out of the circle is centrifical force. If you think in terms of a centrifuge, it spins so fast that the force could push the items out if they were not held down.
The earth's gravitational pull makes objects sink in a liquid, but buoyancy acts in the opposite direction to oppose the gravity. Whether an object sinks or floats depends on which force is bigger. ================================
Gravity is the force which makes a thrown ball fall back to the ground. It is the force which attracts all objects to the Earth.
