The velocity of an object can only change if it is accelerating and if this is constant and continuous. Velocity will also only change direction if acceleration is greater than zero and will not work if at zero.
Depending on when you were born your Sun sign is Scorpio or Sagittarius.
When the potential is decreasing, the electric field points in the direction of decreasing potential.
The unit vector n that points in the direction of propagation is a vector with a magnitude of 1 that indicates the direction in which a wave or signal is moving.
it points in the direction of flowing current due to majority carriers... that is from positive side to negative side
The high points in a transverse wave are called crests. These are the points where the displacement of the medium is at a maximum in the upward direction perpendicular to the direction of wave propagation.
north
The speed is zero at the points where there is a change in direction; thus, at points where the object comes to a temporary stop and reverses direction.

No, distance refers to the amount of ground covered between two points without considering direction. Direction is a separate concept that indicates the orientation of the movement between the two points.
The arrow on a furnace filter points in the direction of airflow.
