Do velocity and acceleration of an object have to be in the same direction?

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.)

What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
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.
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).
How can an object be accelerating while traveling at the same speed?
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
How is direction of acceleration related to direction of momentum?
It isn't. The direction of momentum is the same as the direction of the velocity - of the movement. The direction of acceleration, on the other hand, is the same as the direction of the net force that acts on an object - and this force can be in any direction.
What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
How does acceleration affect motion in the same direction?
It will increase the velocity of the the object in which the acceleration is applied.
What moving object speed up in what direct is the acceleration?
The acceleration is the same direction of the velocity
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.
What is true when the velocity and the acceleration of an object are in the same direction?
In that case, the object speeds up.
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).
If the acceleration of an object is in the same direction as the velocity what happens to the velocity of the object?
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
What will change if a force pushes an object in the same direction as the object's motion?
It will cause acceleration, and increase its velocity.
How can an object be accelerating while traveling at the same speed?
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
How is direction of acceleration related to direction of momentum?
It isn't. The direction of momentum is the same as the direction of the velocity - of the movement. The direction of acceleration, on the other hand, is the same as the direction of the net force that acts on an object - and this force can be in any direction.
Is acceleration always in the same direction as the unbalanced force?
No, acceleration is change in velocity. (And velocity is speed in a certain direction.) If an object slows down, then it is changing velocity and thus accelerating. (In this case, the acceleration is negative.) If an object changes direction, then it's velocity changes, so this is also acceleration. (This is centripetal acceleration.)
How are the direction of the an objects acceleration and direction of the same object change in velocity related?
if the force isnt inline , resolve into axial and lateral forces, the original force bieng the hypotonuse
