SI Unit of Force
The SI unit of force is the Newton (N), named after Sir Isaac Newton. It is defined as the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared.

Explanation
- Newton (N): The Newton is the SI unit of force, representing the amount of force needed to accelerate a one-kilogram mass at a rate of one meter per second squared.
- Derived Unit: The Newton is a derived unit, meaning it is derived from the base units of the International System of Units (SI).
- Relation to Other Units: One Newton is equal to one kilogram meter per second squared (1 N = 1 kg m/s^2).
- Practical Applications: The Newton is commonly used in physics and engineering to quantify forces such as weight, tension, and friction.
- Measurement Tools: Force can be measured using tools such as spring scales, tension meters, and force gauges, all calibrated in Newtons.
- Force Formula: The formula for force is F = ma, where F represents force, m is mass, and a is acceleration.
By understanding the SI unit of force, we can accurately quantify and measure the effects of forces in various scientific and engineering applications.
