SUMMARY

The discussion focuses on calculating wind speeds based on the distance an object moves over time and its weight. A specific example is provided where a 600lb object travels 30 meters in one second, indicating a minimum wind speed of 30 m/s (approximately 70 mph). Key factors influencing the calculation include the coefficient of friction, the object's surface area, and its geometric shape. Additional considerations such as the wind's burst duration are also highlighted as critical for accurate calculations.

PREREQUISITES
  • Understanding of basic physics principles, particularly motion and forces.
  • Knowledge of coefficients of friction and their impact on movement.
  • Familiarity with geometric shapes and surface area calculations.
  • Basic grasp of wind dynamics and burst behavior.
NEXT STEPS
  • Research the physics of motion to understand the relationship between force, mass, and acceleration.
  • Study the coefficients of friction for various materials to apply in calculations.
  • Learn how to calculate surface area for different geometric shapes relevant to wind resistance.
  • Explore wind dynamics, particularly the effects of wind bursts on object movement.
USEFUL FOR

Engineers, physicists, meteorologists, and anyone involved in calculating wind effects on objects, particularly in fields like aerospace, automotive design, or environmental science.

This is pretty simple,but finding the correct formula does not seem to be that easy for me.

How could I calculate wind speeds with only having the distance an object moved over a certain amount of time and the weight of said object?

For example,winds caused a 600lb object to travel 30 meters in a second.

How would I approach this?

That's really not enough information to tell you anything, other than that the wind speed would need to be at least 30 m/s (which is a pretty strong wind - that's almost 70mph minimum).
 
What else would be needed?Ok I will draw a model to better depict what I am talking about.
 
Alright, here we are.

The object moves on the floor? You need the coefficient of friction of the object on the ground, the surface area of the object in the wind and its geometric shape, in addition to the parameters you already have.

It is easier to you throw some light object in the air - it will fly with the velocity of the wind.
 
Why would the object stop after 30m? Is the wind blowing in short bursts? Then the distance will depend on the duration of the burst.
