The gravitational force is always attractive.
No, all objects in the Universe generate a pulling force on all other objects. The Moon, Sun, planets, asteroids, meteors and stars all have a gravitational field. All humans, animals, trees, planes and buildings possess a gravitaional force, relative in size to its mass.
Freefall this means the objects is falling through the air while gravity is pulling.
False. Every object attracts every other object, through the gravitational force.
One such force is gravity; basically, gravity is the ONLY force that affects ALL objects.
Gravitation is the only force that acts universally.
In Newton's third law of motion, only two objects are involved in producing an action-reaction pair. When one object exerts a force on a second object, the second object simultaneously exerts an equal and opposite force on the first object.
No. All planets, moons, and stars have gravity. Techincally, anything with mass has gravity, but it is only noticeable with very large objects.
Objects on Earth do not float because of gravity. The force of gravity pulls objects toward the center of the Earth, causing them to sink. Objects will only float if the force of buoyancy pushing them upward is greater than the force of gravity pulling them downward.
Freefall this means the objects is falling through the air while gravity is pulling.
I wasn't there, so I have no knowledge of how things were set up in that particular experiment. The only force I'm sure of is the force of gravity, and your use of the term "dropped" seems to confirm that assumption.
Freefall this means the objects is falling through the air while gravity is pulling.
False. All objects with mass exert gravitational forces on each other, not just the Earth.
