When a force acts upon an object, and that force is great enough to overcome initial friction, the object will undergo an acceleration until the force is removed or is balanced by another force.
Gravity is NOT matter, it is a force that effects matter.
Yes, dark matter exerts gravitational force, even though it does not emit or interact with light. Its presence can be inferred through its gravitational effects on visible matter and light.
The effects of force on a mass is acceleration of the mass.
A black hole is a void in space-time where gravity is so strong that no matter or energy can escape the effects of its force.
Stars, gas, and dust are all categorized as visible matter, not "dark" matter, but, since dark matter does not interact electromagnetically, the behavior of ordinary matter is used to study dark matter through their gravitational effects. You might say that stars, gas, and dust are like the leaves blowing in an invisible wind; the force can be perceived by the effects on the leaves even if you can't see the wind directly.
Force is energy
Dark matter and The Force are not the same thing. The Force is a fictional power that connects all things. Dark matter is a real-world, theoretical matter that figures into physics and mathematics.
No.
Gravitational force is the atraction of all matter to all other matter
no force on a matter means there are no physical quantities which affect the motion, shape and size of that matter.
Force
A force acting on a body accelerates it in the direction of the force.
