Question

Что такое скорость в физике???????

Answer 1

В физике скорость - это векторная величина, характеризующая быстроту перемещения материальной точки относительно выбранной системы отсчёта. По определению, равна производной радиус-вектора точки по времени. В СИ измеряется в метрах в секунду.

Answer 2

What is speed in physics?

In physics, speed is a fundamental concept that measures how quickly an object moves. It is defined as the distance traveled by an object per unit of time. Speed is a scalar quantity, meaning it only has magnitude and no direction.

The formula to calculate speed is:

Speed = Distance / Time

Where: - Speed is the rate at which an object covers distance. - Distance is the total path traveled by the object. - Time is the duration it takes for the object to travel that distance.

Speed is typically measured in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph), depending on the context.

It's important to note that speed is different from velocity. While speed only considers the magnitude of the motion, velocity takes into account both the magnitude and direction of the motion.
