velocity
It is called VELOCITY
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
The rate at which an object covers distance is called the object's "speed".If the direction of its motion is also stated, then you have the object's"velocity".
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
If you apply force in the same direction an object moves, the work on the object is positive.If the force is in the opposite direction as the direction the object moves, the work on the object is negative.

speedIn physics:If the direction doesn't matter, the word "speed" is used.If the direction DOES matter, the word "velocity" is used.

in terms of speed and direction , in what ways can an object accelerate
If you apply force in the same direction an object moves, the work on the object is positive.If the force is in the opposite direction as the direction the object moves, the work on the object is negative.
There is no special equation. But to fully specify a velocity, you need to know an object's speed as well as the direction in it moves.
it moves ----------> there for if you were to push the object it will go <--------
'Speed' . If you also specify the direction in which it moves by that distance, then you have 'velocity'.
speed=distance divided by time........Hewitt describes it as how fast something moves; the distance an object travels per unit of time; the magnitude of velocity !!... and velocity is the speed of an object and its direction of motion ; a vector quantity. SO .....YES!!!!!!!!!!!
As used in physics, "speed" is just how fast something moves, without considering the direction; whereas "velocity" also considers the direction. In other words, speed is a scalar, while velocity is a vector.
