The difference between speed and velocity is an important concept in physics. Both describe motion, but they are not the same.AkLeraningNepal
Speed
Speed is the rate at which an object covers distance. It tells us how fast an object is moving, but not the direction.
- It is a scalar quantity
- Depends only on distance travelled
- Direction is not required
Velocity
Velocity is the rate of change of displacement with time. It tells us both the speed of an object and the direction of motion.
- It is a vector quantity
- Depends on displacement
- Direction is always required
Note:
Speed can never be negative, but velocity can be positive, negative, or zero depending on direction.
