Question

What is speed . what is average speed.​

Answer 1

Answer:

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. Lower speed means it is moving slower. If it isn't moving at all, it has zero speed.

The most common way to calculate the constant velocity of an object moving in a straight line is the formula:

Answer 2

$\textsf{Speed:-}$

The measurement of distance travelled by a body per unit time.

$\text{SI\:unit:-}$ Meter/second (m/s).

=> If a body is executing uniform motion, then there will be a constant speed or uniform motion.

=> If a body is travelling with non-uniform motion, then the speed will not remain uniform but have different values throughout the motion of the body.

$\textsf{Average\:Speed:-}$

Total distance travelled/ total time taken
