Velocity is just speed but with a direction. As the object goes up, the velocity will be in the same direction as the object travels (up, which is +ve). At the highest point, the object is not moving. And on the way down, the object is moving down, so you can figure the velocity, right?Gilly1998 said:
Anytime an object is moving upwards, its velocity is +ve. Anytime it's moving downwards, its velocity is -ve. If it's not moving, its velocity is zero. So when the object returns to you hand, its velocity is -5m/s. (Same speed as when it left your hand, but opposite direction). Hope you get it now...Gilly1998 said:

An object's velocity refers to the rate at which it changes its position in a particular direction. It is a measure of how fast an object is moving and in what direction.
When an object's velocity is up, it means that it is moving in the positive direction of the chosen coordinate system. This could be up, down, left, right, etc. It is important to note that velocity is a vector quantity and includes both a magnitude (speed) and a direction.
The highest velocity an object can have is the speed of light, which is approximately 299,792,458 meters per second. This is considered the maximum speed limit in our universe and is only achievable by massless particles.
When an object is moving downward, its velocity is negative in the chosen coordinate system. This means that the object is moving in the opposite direction of the positive direction. For example, if an object is moving downward in the y-direction, its velocity would be negative in the y-direction.
An object's velocity determines its overall motion. If an object has a constant velocity, it will continue to move at that speed and in the same direction. If an object's velocity changes, its motion will also change. For example, if an object's velocity increases, its motion will become faster. If an object's velocity decreases, its motion will become slower.
