To drive onto a moving object (as, for example, up a ramp onto a moving trailer), you must be going faster than the object to move forward up the ramp, but when you come to a stop relative to the object, you will be moving with the object, so must be moving at the same speed. You must, in fact, decelerate to a stop on the object, or your faster approach speed would carry you through and beyond it.
The speed of an object moving in a specific direction is called its velocity. Velocity is a vector quantity that describes both the speed of the object and the direction in which it is moving. Speed only describes how fast an object is moving without specifying the direction.
Velocity, or Speed
The object's motion is described by its velocity, which includes both speed and direction. The speed tells us how fast the object is moving, while the direction indicates the path it is following.
Speed is a scalar quantity that measures how fast an object is moving, regardless of direction. Velocity, on the other hand, is a vector quantity that includes both the speed of an object and the direction in which it is moving. So, while speed tells you how fast an object is moving, velocity tells you both how fast and in what direction it is moving.
Speed. (not velocity)
speed How fast in which direction is velocity.
speed How fast in which direction is velocity.

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. ... An object with no movement at all has a zero speed.
The property of motion that describes how fast an object is moving is known as speed. Speed is a measure of the distance traveled by an object in a given amount of time.
Stataneous speed refers to the speed of an object at a particular instant in time. The speed could be fast or slow depending on the object and context in which it is moving.
Velocity is the speed of an object in a specific direction. It includes not just how fast an object is moving, but also the direction in which it is moving.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
