# Difference between Centre of Gravity and Centroid

When it comes to physics and engineering, you may have heard the terms “center of gravity” and “centroid” used.

The main difference is that center of gravity refers to the point where the weight of an object is concentrated while centroid refers to the geometric center of a shape or object.

Before we move to the differences, let’s understand what are Centre of Gravity and Centroid:

• Centre of Gravity: The center of gravity is the point on an object where the force of gravity appears to act. It is the point where the weight of the object can be considered to be concentrated.
• Centroid: The centroid is the geometric center of a shape or object. It is the point where all the lines of symmetry intersect. Now, let’s move to Centre of Gravity vs Centroid:

## Major differences between Centre of Gravity and Centroid

Centre of Gravity Centroid
Center of gravity refers to the point where the weight of an object is concentrated. Centroid refers to the geometric center of a shape or object.
Center of gravity is a physical concept. Centroid is a geometric concept.
Center of gravity is influenced by the distribution of mass within an object. Centroid is influenced by the shape and dimensions of the object.
Center of gravity can be located outside the physical boundaries of an object. The centroid is always located within the boundaries of the object.
Center of gravity is important for understanding the stability and balance of an object. Centroid is important for determining the balance and symmetry of a shape.

That’s it.

Note that sometimes, the question might also be asked as “distinguish between Centre of Gravity and Centroid”.

## Final words

Center of gravity and centroid are two different concepts used in physics and engineering.

While the center of gravity is influenced by the distribution of mass within an object and is important for understanding its stability and balance, the centroid is influenced by the shape and dimensions of an object and is important for determining its balance and symmetry.
