Final answer:
Velocity is a vector quantity that describes the speed and direction of an object. It can be calculated by dividing displacement by time. Vectors can be represented using component vectors.
Step-by-step explanation:
Velocity is a vector quantity that describes the speed and direction of an object. It is represented by a vector, which has both magnitude and direction. For example, if a car is traveling east at 100 km/h, the velocity of the car is 100 km/h in the eastward direction.
Velocity can be calculated by dividing the displacement of an object by the time taken. It is important to note that velocity is independent of the path taken and can be positive or negative, depending on the direction of the object's motion.
When working with vectors, it is common to represent them using component vectors. In two dimensions, the velocity vector can be separated into its x-component (Vx) and y-component (Vy), which are vectors in their respective directions.
