Velocity is a magnitude that describes the rate of change of the position of an object. In other words, it tells us how quickly an object is moving from one point to another.
Formula:
Velocity (v) = Distance traveled (d) / Time taken (t)
where:
v is the velocity in meters per second
d is the distance traveled in meters
t is the time taken in seconds
Examples:
If an object travels 10 meters in 2 seconds, its average velocity is 5 m/s.
If an object starts at rest and moves 20 meters in 4 seconds, its average velocity is 5 m/s.
If an object moves from point A to point B along a curved path in 3 seconds, its average velocity will be different depending on the shape of the path.
Key Points:
Velocity is a vector quantity, meaning it has both magnitude and direction.
It is a qualitative measure, meaning it tells you how fast an object is moving, but not how far it has gone.
Velocity can be positive or negative, depending on the direction of motion.
Velocity can be calculated from the instantaneous position and instantaneous velocity of an object
