Answer 1

скорость движения u равна отношению расстояния s к времени движения t

 

u=s/t

Answer 2

Formula for Speed

The formula for speed is given by the equation:

u = s / t

Where: - u represents the speed - s represents the distance - t represents the time taken

This formula indicates that speed is equal to the ratio of distance to the time taken for the movement.

Explanation of the Formula

The formula u = s / t represents the fundamental relationship between speed, distance, and time. It states that the speed of an object is determined by the distance it travels in a certain amount of time. The greater the distance covered in a given time, the higher the speed.

Units of Measurement

The units of measurement for speed, distance, and time are crucial in using this formula effectively. Typically, distance is measured in meters (m) or kilometers (km), and time is measured in seconds (s), minutes (min), or hours (h). As a result, the unit for speed can be meters per second (m/s), kilometers per hour (km/h), or other similar units depending on the specific context.

Example Calculation

For instance, if a car travels a distance of 100 kilometers in 2 hours, the speed can be calculated using the formula u = s / t as follows:

u = 100 km / 2 h = 50 km/h

This means the car's speed is 50 kilometers per hour, indicating the distance it covers in one hour.

Relativity and Speed of Light

It's important to note that the formula for speed discussed here applies to everyday speeds and is consistent with classical mechanics. However, at very high speeds approaching the speed of light, the formula for speed undergoes modifications due to the principles of special relativity. At such extreme speeds, the behavior of space and time becomes non-intuitive, and the formula for speed is adjusted to accommodate these relativistic effects.

Conclusion

In summary, the formula u = s / t provides a fundamental relationship between speed, distance, and time. It is a key concept in physics and is used to calculate the speed of an object based on the distance it travels and the time taken to cover that distance.
