The magnitude of velocity is the speed of an object in a given direction. It is a measure of how fast an object is moving without considering its direction.
The magnitude of velocity is calculated by dividing the total distance traveled by the total time taken. This gives the average speed of the object. The direction of the velocity is not taken into account in this calculation.
A negative magnitude of velocity indicates that the object is moving in the opposite direction of the chosen positive direction. For example, if the positive direction is east and the object has a velocity of -10 m/s, it means the object is moving west at a speed of 10 m/s.
The magnitude of velocity takes into account the direction of the object's motion, while speed only measures the rate of motion without considering direction. This means that two objects can have the same speed, but different magnitudes of velocity if they are moving in different directions.
The direction of velocity is represented by a vector, which includes both magnitude and direction. The direction can be indicated using a compass direction (e.g. north, south, east, west) or an angle measured from a reference point (e.g. 45 degrees north of east).
