Velocity is a vector quantity that describes the rate at which an object changes its position in a specific direction. It is typically measured in units of distance per time, such as meters per second (m/s) or miles per hour (mph).
To calculate the velocity of an object, you need to know the object's initial position, final position, and the time it takes for the object to move from the initial position to the final position. The formula for velocity is:
Velocity = (final position - initial position) / time
For example, if an object starts at position x1 = 5 m and ends at position x2 = 10 m, and it takes 2 seconds for the object to move from x1 to x2, the velocity of the object would be:
Velocity = (10 m - 5 m) / 2 s = 2.5 m/s
It is also important to note that velocity is a vector quantity, meaning that it has both a magnitude (size) and a direction. This means that the velocity of an object is different depending on which direction the object is moving.
