Here's why:
* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Speed is a scalar quantity, meaning it only has magnitude.
* Instantaneous velocity is the velocity of an object at a specific point in time.
* Instantaneous speed is the magnitude of the instantaneous velocity, meaning it tells you how fast the object is moving at that specific moment without considering its direction.
In simpler terms:
Think of a car driving down the road. At any given moment, the car has a certain speed (how fast it's moving) and a certain direction (which way it's going). The instantaneous velocity captures both of these aspects, while the instantaneous speed only tells you how fast the car is moving at that exact moment.
