The major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
1. **Speed**: This refers to how fast an object is moving, regardless of its direction. It is defined as the distance traveled per unit of time. Speed is expressed as a single numerical value (e.g., 50 km/h) and does not contain any directional information.
2. **Velocity**: This refers to the rate at which an object changes its position, taking direction into account. Velocity is defined as displacement (the change in position) per unit of time. It is expressed as a numerical value with a direction (e.g., 50 km/h east).
In summary, while speed tells you how fast something is moving, velocity tells you both how fast and in which direction it is moving.
