What happens to gravity in vacuum?
In a vacuum, where there is no air or matter, gravity still exists and continues to exert a force on objects. The absence of air resistance may result in faster acceleration of objects in a vacuum compared to in the presence of air.
What is the definition of gravity and how was it formed?
Gravity is the force that attracts two bodies towards each other. It was formed due to the uneven distribution of mass in the universe, causing objects with mass to exert a gravitational pull on each other. This force of gravity keeps celestial bodies in orbit and governs the motion of objects on Earth.
When two objects are not moving relative to one another but are still in contact the force that's resists the initiation of a sliding motion is?
Friction
What has more momentum than a car type of friction between stationary objects?
The type of friction between stationary objects that has more momentum than a car is static friction. Static friction occurs when two surfaces are not moving relative to each other but still exert a force in opposition to any impending motion. It requires more force to overcome static friction compared to kinetic friction.
Why do objects accelerate during free fall?
Earth's gravity pulls all objects toward its center of mass, or in most cases toward the surface. Gravity is a property of matter,and causes every mass to exert a force on every other mass. In this case, the Earth's gravity applies a force to every object on it, and that force will accelerate an object toward the Earth's center, unless it is prevented by some intervening mass. It will still have the potential to accelerate again if the intervening mass is removed.
Because the sun is so far away it does not exert a gravitational force on the earth?
Actually, the sun's gravitational force is what keeps Earth in orbit around it. The force of gravity decreases with distance, but it still influences objects at a considerable distance like the Earth.

Your sun and any star far away in another galaxy despite being very far apart still feel a gravitational force between them?
Yes, all objects with mass exert a gravitational force on each other regardless of the distance between them. This force follows the universal law of gravitation, which states that the force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. This explains why the sun and a star in another galaxy can still feel each other's gravitational pull, even if they are very far apart.

What types of objects experience gravitational forces?
All objects on Earth experience gravitational force to a certain degree. Earth's atmosphere grants it's objects a great gravitational force.+++"All objects throughout the Universe experience gravitational force... " Not just on Earth. The Earth's orbit around the Sun is a function of the Earth's velocity and the Sun's gravity.The Earth's atmosphere does NOT "grant" any gravitational force of its objects (whatever those may be), but is itself subject to the gravity of the planet; hence both it still being here, and exerting a mean pressure of I Bar (by definition) or 100kPa at sea-level.

What force does earth attracts another object towards itself?
The force that Earth uses to attract objects towards itself is called gravity. This force is dependent on the masses of the objects and the distance between them, as described by Isaac Newton's law of universal gravitation.
Why do objects accelerate during free fall?
Earth's gravity pulls all objects toward its center of mass, or in most cases toward the surface. Gravity is a property of matter,and causes every mass to exert a force on every other mass. In this case, the Earth's gravity applies a force to every object on it, and that force will accelerate an object toward the Earth's center, unless it is prevented by some intervening mass. It will still have the potential to accelerate again if the intervening mass is removed.
Is there more force created when 2 objects meet in motion or when 1 object is still?
Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.
Does force and motion apply in space?
Yes, force and motion still apply in space. Objects in space are affected by forces such as gravity, friction, and momentum, and will continue to move or change direction based on these forces. However, since space is a vacuum, there is very little resistance to motion, so objects can continue moving at a constant velocity unless acted upon by another force.
