Any falling object has acceleration and velocity vectors in the same direction.
A moving object with velocity and acceleration vectors in the same direction is accelerating in the direction of its motion. This means that its speed is increasing as it moves in a straight line.
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.
Yes, acceleration is a vector quantity that involves both magnitude and direction. It indicates the rate of change of velocity with respect to time and can be positive or negative, depending on whether it is in the same direction as the velocity (positive) or opposite direction (negative).
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
Acceleration is the rate of change of velocity over time, while velocity is the rate of change of position over time. Both acceleration and velocity are vector quantities, meaning they have both magnitude and direction. Acceleration can either be in the same direction as velocity (causing an increase in speed) or in the opposite direction (causing a decrease in speed).

Moving in the positive direction at an increasing speed. (Accelerating positively)
No. Acceleration only affects velocity in one particular direction (same direction as acceleration). Speed is the summation of velocities in all directions.
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
The velocity vector of an object that is speeding up to the right points in the same direction, to the right. Velocity is a vector quantity that includes both magnitude (speed) and direction, so as the object accelerates, the velocity vector will align with the direction of motion.
Acceleration is the rate of change of velocity over time, while velocity is the rate of change of position over time. Both acceleration and velocity are vector quantities, meaning they have both magnitude and direction. Acceleration can either be in the same direction as velocity (causing an increase in speed) or in the opposite direction (causing a decrease in speed).
That's only true when the object is in circular motion.The circular motion is the result of a force (which produces acceleration)that's always perpendicular to the object's velocity.Like the gravitational force between the Earth and a geostationary satellite,or the tension in the string of a yo-yo that's doing circles.
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
Yes because velocity vector is got by the product of acceleration vector and time which is scalar. v = a t (Except when you toss a ball upward, and until it reaches the top, it has upward velocity and downward acceleration. But in all other situations except for that one.) (And except when a yo-yo or an artificial satellite is moving in a circle, and its velocity is always tangent to the circle but its acceleration is always toward the center of the circle. But definitely in all other situations except for that one.)
The answer is velocity.
