What Is the Difference between Speed and Velocity?
Answer – Speed is solely about how fast something is moving, while velocity not only includes speed but also specifies the direction of motion.
Explanation:
While speed and velocity are often used interchangeably, they have distinct meanings:
Speed:
- Speed is a scalar quantity that measures how fast an object is moving along a path.
- It is the rate at which an object covers distance over time, without considering direction.
- For example, 50 km/hr represents the speed of a car traveling along a road.
Velocity:
- Velocity is a vector quantity that includes both the speed and direction of an object’s movement.
- It describes how fast an object’s position changes with respect to time.
- Velocity is calculated by considering both the magnitude (speed) and direction of motion.
- For instance, 50 km/hr west indicates both the speed and direction of an object’s movement.
