Where is the acceleration directed during the rectilinear motion of the body, if the modulus of its velocity increases? Decreases?

1. With an increase in the modulus of speed, acceleration a> 0, the acceleration vector is directed in the same direction as the x-axis, that is, the vectors of velocity and acceleration are directed in the same direction.
2. When decreasing the modulus of velocity a <0, that is, accordingly, that the acceleration vector is directed in the opposite direction relative to the x-axis, and therefore the vectors of velocity and acceleration are directed in different directions.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
