What is the SI unit of force?

The SI unit of force is the Newton (N).

The Newton is defined as the force required to give a mass of 1 kilogram an acceleration of 1 metre per second squared. This means that if a force of 1 Newton is applied to an object with a mass of 1 kilogram, the object will accelerate at a rate of 1 metre per second squared.

The Newton is named after Sir Isaac Newton, who is famous for his laws of motion. These laws describe how objects move and interact with each other in the presence of forces.

In addition to the Newton, there are other units of force that are used in different contexts. For example, the pound-force (lbf) is commonly used in the United States and the poundal (pdl) is used in some scientific applications. However, the Newton is the standard unit of force in the International System of Units (SI).

Understanding the unit of force is important in many areas of physics, including mechanics, thermodynamics, and electromagnetism. It allows us to quantify the effects of forces on objects and to make predictions about how objects will behave under different conditions.
