Does net force cause displacement?
Basically, a net force causes an acceleration - a change in velocity. Over time, this must needs cause a displacement.
How do collision exemplify the law of conservation of momentum?
The vector sum of momenta before and after the collision is the same. One way to visualize this is that if one of the colliding objects changes its momentum (mass x velocity) in one direction, then the other colliding object must needs change its momentum in the opposite direction - by the same amount, except for the direction.

What do you need to know describe the velocity of an object?
velocity is what is known as a vector quantity. What this means is it needs both a DIRECTION and a MAGNITUDE for the velocity to be fully described. that's what you need.
Relationship between force and motion?
An object will only change its motion if undergoing a force acting upon it. An object does not, necessarily, need a force to act upon it to move; it needs only a force to accelerate (or decelerate!) If dealing with an object at rest, this equation works best to describe how that object can begin to move: F = ma Where F is the force applied, m is the mass of the object, and a is the acceleration. Therefore, if you apply a force of 10 Newtons to a mass of 10 Kilograms constantly, the object will undergo uniform acceleration of 1 m/s^2 -- ie, it will increase its velocity by 1m/s (meter per second) every second. A force does not need to be constantly applied to an object for it to continue to move. If a force of 10 Newtons is applied to an object of mass 10 kilograms for just one second, the object will accelerate to AND THEN REMAIN AT the velocity 1 meter per second. Now, if you're dealing with objects already moving, the equation looks a little different: it's called the impulse equation, and it describes the relationship between forces and objects in the context of a CHANGE OF MOTION (or, specifically, momentum.) It reads as follows: FT = m(Vf - Vo) F and m are the same as above. Essentially, this equation describes the change in motion--starting at "Vo" and ending with "Vf" of an object mass "m" when the force "F" is applied for "T" seconds. That's really all there is to know--for LINEAR motion, which I assume you're referring. If you mean angular motion, that's another ballgame, and one I really don't want to get involved with ;)
In order to change the velocity there needs to be a?
To need force
Do objects in motion always change position and may change direction?
Objects in motion continuously change position.To change direction, a force needs to act upon them.
What is the velocity a rocket needs to reeach to orbit in space called?
Escape velocity.
What happens to a room once you leave it?
It stays the way you left it, unless someone else enters and modifies the room according to the person's or thing's needs, then the room will be left exactly as they were last modified and will not change until otherwise force is applied to the objects in the room, altering its formation and appearance

How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
