One kilogram-meter per second squared is also equal to what unit
The correct answer and explanation is:
Correct Answer: Newton (N)
One kilogram-meter per second squared (1 kg·m/s²) is the definition of one Newton (N), which is the SI unit of force.
To understand this, it is helpful to look at Newton’s Second Law of Motion, which states:
Force = Mass × Acceleration
In this equation:
- Mass is measured in kilograms (kg)
- Acceleration is measured in meters per second squared (m/s²)
- Therefore, force is measured in kilogram meters per second squared (kg·m/s²)
This derived unit was given the name Newton (N) in honor of Sir Isaac Newton. So, by definition:
1 Newton (N) = 1 kg·m/s²
The Newton is part of the International System of Units (SI) and is widely used in physics, engineering, and other scientific disciplines. It allows scientists and engineers to express force in a standard and consistent way.
For example, if an object with a mass of 1 kilogram is accelerating at a rate of 1 meter per second squared, the force acting on it is exactly 1 Newton. This can be observed when pushing a small object on a frictionless surface.
Using standard units like the Newton helps avoid confusion and ensures compatibility of measurements across different fields and countries. The concept of using a derived unit like this makes calculations and communication easier in both theoretical and applied sciences.
So, the unit kilogram-meter per second squared (kg·m/s²) is exactly the same as 1 Newton, and both represent a measure of force.
