Why can velocity be negative or positive?
Yes, "velocity" is a vector so it not only has magnitude but also direction. By convention, an object moving from left-to-right or upward is moving in a positive direction while an object moving right-to-left or downward is moving in a negative direction. "Speed" is a related term but it is a scalar. As such, it has only magnitude. A speed cannot be negative.
What would be the acceleration of a turtle that is moving with a constant velocity of 0.191 meters per second to the right?
If he is moving at a constant speed and not changing direction, then acceleration is zero.
What is the difference between relative velocity and absolute velocity?
One pretty important difference is that relative velocity exists and absolute velocity doesn't. Velocity is always measured and described relative to something. There's no such thing as the "real speed" of a moving object. In fact, according to a scientist who's riding on the object, it's not moving at all. (Close your eyes right now and feel the earth move ?)
What is the oppostition to electron flow?
Imagine I have 3 empty boxes in a line, touching, like so |_| |_| |_|. I am labeling the first box to the left A, the middle one B, and the right one C. Then I put one marble in A and one in B. C is empty. So the drawing becomes |X| |X| |_|. Next, I remove the marble in B and place it in C. The drawing looks like |X| |_| |X|. I can say the marble has moved one step to the right. I can also say the space has moved one step to the left. In electronics, an electron is like a marble. We describe the empty box (void) as a hole. An electron moving to the right is equivalent to a hole moving to the left.
If a ball is rolling in a straight line and you push it to the right velocity Will?
If a ball is rolling in a straight line and you push it to the right velocity will accelerate.
What would the acceleration of a turtle that is moving with a constant velocity of 0.25 miles per second to the right?
The acceleration would be zero because the turtle is moving at a constant speed
How do you get the velocity of a grape?
it depends on the situation the grape is in! Velocity is the change in distance / change in time... for example: if a car moves 3 meters in 1 second. the car has a velocity of 3 m/s... or 6 meters in 2 seconds.. its velocity is still 3m/s velocity is a vector quantity however so you must be careful while solving velocity related problems... basically this means that velocity is also measured by which direction the object is moving.... if the car from the previous example is moving to the right, its velocity would be +3m/s.... if it were moving to the left it would be -3m/s. (moving left or right is all relative to the starting position of the car).

What would happen to a marble if dropped into an empty container like a beaker while the person dropping it was in motion?
The marble will have the motion of the person who dropped it (I assume you mean by 'dropped' that it is not thrown by the person, just dropped), whilst I assume the beaker is stationary. I also assume the person is moving horizontally and the beaker is upright. Therefore the marble will arrive in the beaker with some sideways velocity and will strike the side of the beaker with a horizontal component of velocity as well as a vertical component. I should think it will spin round the beaker a few times before coming to rest, it might even bounce right out. You can't predict this exactly without some more information.
What would be the acceleration of a object that is moving with a constant velocity of 0.25 minutes to the right?
1). If neither speed nor direction are changing, then acceleration is zero.2). "minutes" is not a unit of velocity, but we get the idea

If velocity increases this is called?
If speed increases, or if the moving object curves up or down or to the right or to the left, or if speed decreases, any of these events is called "acceleration".
Is this a metaphor her eyes had turned to marble?
no, its not. if you said her eyes are marble then yes. right now you're just stating that her eyes have changed into marble, like a freak accident.
Under what conditions is the velocity of a body negative?
Generally, north, east, right, and forward are considered positive directions. South, west, left, and backward are considered negative directions. So if a body is moving south, west, left, or backward, its velocity is considered to be negative.
If a ball is rolling in a straight line and you push it to the right velocity Will?
If a ball is rolling in a straight line and you push it to the right velocity will accelerate.
