The concept of velocity is an important aspect of motion. While speed measures how fast an object is moving, velocity takes into account both speed and direction. Velocity is a vector quantity, meaning it has both magnitude and direction.

To calculate velocity, we use the formula velocity = displacement/time. Displacement refers to the change in position of an object, which can be determined by subtracting the initial position from the final position.

For example, let's say an object starts at position 2 meters and moves to position 6 meters in 2 seconds. The displacement would be 6 - 2 = 4 meters. Dividing this displacement by the time interval of 2 seconds gives us a velocity of 2 m/s.

It's important to note that velocity considers both the magnitude (speed) and the direction. For instance, an object moving at a speed of 3 m/s to the right and another object moving at a speed of 3 m/s to the left would have different velocities due to their opposing directions. Therefore, to fully describe the velocity of an object, we must include both the magnitude and the direction.
