What Is The Dimension Of Force?

Are you curious to know what is the dimension of force? You have come to the right place as I am going to tell you everything about the dimension of force in a very simple explanation. Without further discussion let’s begin to know what is the dimension of force?

What Is The Dimension Of Force?

Force is a fundamental concept in physics, central to understanding the motion and interaction of objects in our universe. To describe and quantify this physical quantity, scientists use dimensions. In this blog post, we will explore what the dimension of force is and how it is represented, shedding light on its significance in the world of physics.

Defining Force

Force, in the context of physics, is defined as a push or pull on an object resulting from the interaction between two objects. It is a vector quantity, which means it has both magnitude (size or strength) and direction. Forces can cause objects to move, accelerate, decelerate, or change their direction of motion.

Dimensions In Physics

In physics, dimensions are used to describe and quantify physical quantities. These dimensions are essentially units of measurement that enable us to express a physical quantity in a standardized way. There are several fundamental dimensions in physics, including length (L), mass (M), time (T), temperature (Θ), electric current (I), and luminous intensity (J). These dimensions serve as the building blocks for defining other physical quantities.

Dimension Of Force

The dimension of force is derived from Newton’s second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. Mathematically, this law is expressed as:

F = ma


  • F represents force (in newtons, N),
  • m represents mass (in kilograms, kg), and
  • a represents acceleration (in meters per second squared, m/s²).

By examining the units of mass, acceleration, and force, we can determine the dimension of force. Let’s break it down:

  1. Mass (M): The dimension of mass is expressed as [M].
  2. Acceleration (L/T²): The dimension of acceleration involves length (L) divided by time squared (T²).
  3. Force (M*L/T²): Combining the dimensions of mass (M) and acceleration (L/T²), we get the dimension of force as [M*L/T²].

Therefore, the dimension of force is represented as [M*L/T²].

In the International System of Units (SI), which is the standard system of measurement in physics, the unit of force is the newton (N). One newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared:

1 N = 1 kg * 1 m/s²


Understanding the dimension of force, represented as [M*L/T²], is crucial for physicists and engineers as it allows them to quantify and express force in a consistent and standardized manner. Force, being a fundamental concept in physics, plays a pivotal role in the study of motion, mechanics, and the behavior of objects in the universe. Whether it’s the force of gravity, friction, or any other interaction, the dimension of force helps scientists analyze and describe these phenomena accurately.


What Is Dimensional Formula?

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is. F = [M L T-2] It’s because the unit of Force is Netwon or kg*m/s2. Dimensional equation.

Is Force A Basic Dimension?

Using this convention, force becomes a function of length, mass, and time (i.e., force is equal to mass multiplied by length all divided by time squared) and is not considered a base definition. However, others can choose to define force as one of their base dimensions.

What Is One Dimensional Force?

Forces can be classified several ways: A force is a push, a pull, a bend or a twist. Force is a vector quantity, and therefore needs magnitude and direction. Force is measured in newtons (N).

What Are Forces In Two Dimensions?

When looking at forces in two dimensions, a force can point along the x or y axis, or at any angle in between. The net force acting on an object is found by adding all the forces acting on that object using vector addition.
