Question

distinguish between speed and velocity ​

Answer 1

SPEED

Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Higher speed means an object is moving faster.

VELOCITY

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).

In SI base units:m/s

Other units:mph, ft/s

Common symbols:v, v, v→

Answer 2

Answer:

Speed:-

1. Speed:-The distance covered per unit time is called speed of an object.
2. Speed has magnitude but no direction.
3. Speed is a scalar.
4. Average speed =Total distance/Time taken.

Velocity:-

1. Velocity:-Velocity is the displacement per unit time.
2. Velocity has both magnitude and direction.
3. Velocity is a vector.
4. Average velocity=Displacement/Time taken.
