What is a moving object that has a velocity vector and acceleration vector in the same direction?
The net force is in the same direction as the acceleration of an object.
If an object is moving at a constant velocity and you want to change it's momentum you would change it's?
The answer is velocity.
Why is Acceleration vector quantity?
That simply means that the direction of the acceleration is relevant. For example, if something is moving in the "forward" direction, it isn't the same if we accelerate it forward, backward, or sideways. The results are different.Also, acceleration is calculated as dv/dt, meaning you divide a velocity difference by a time. Since velocity is itself a vector, acceleration is also a vector.
What is the relationship between speed velocity and acceleration?
velocity (v) = initial velocity (v0) + acceleration (a) x time (t); that is v = v0 + at. The relation is the same for speed ( a scalar) which is velocity ( a vector) without direction assigned; velocity = speed
How can an object stay at same speed and still be accelerating?
acceleration is change in velocity over time. It is important to know that speed is not a vector quantity; it is scalar (meaning it does not have direction), -- velocity does. Therefore, speed is only the MAGNITUDE of velocity. Also, acceleration is a vector quantity meaning it has both magnitude and direction. If you change EITHER magnitude or DIRECTION, acceleration changes. Okay anyway to answer your question, You can have the same magnitude of velocity (aka same speed) and still be accelerating if YOU CHANGE DIRECTION. --- gh

What is an object that has velocity and acceleration vector going the same direction?
Moving in the positive direction at an increasing speed. (Accelerating positively)
Are acceleration and speed always in the same direction?
No. Acceleration only affects velocity in one particular direction (same direction as acceleration). Speed is the summation of velocities in all directions.

What is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
Is the direction of velocity is same as direction of acceleration?
obviouslly not. there are many cases where the velocity is present but not acceleration and vce versa. it is also applicable for the direction of the measurements.
Are the direction of the velocity and acceleration of a falling body the same?
For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.
Is vector the same as velocity?
No. A vector is any measurement where a direction is relevant. Velocity is one such measure, but there are others, unrelated to velocity (for instance, force).
