the object's velocity
Velocity
Some of the more basic measurements of an object we can take are time and position (or distance). From these values we can calculate things (like speed and direction) that we use to describe its motion.
The speed increases. The object accellerates positively in the direction of motion.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".

When a moving object is pushed in the direction of its motion the speed of the object increases
When a moving object is pushed in the direction of its motion the speed of the object increases
If the speed of an object is cited and its direction of motion is also cited, we have the velocity of the object. Velocity is speed plus a direction vector.
The speed increases. The object accellerates positively in the direction of motion.
If you know the speed and direction of the object's motion, then you know its velocity.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Speed and direction is called velocity.
This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
