#### Center of mass equation physics

## What is the center of mass in physics?

The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.

## What are the factors that effect of the center of mass?

What are the factors that effect of the center of massmass of rigid body.position of mass from axis.axis of system.distribution of mass.

## What is difference between Centre of mass and Centre of gravity?

Centre of mass is the point at which the distribution of mass is equal in all directions and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions and it does depend on gravitational field.

## Does the center of mass change?

Center of mass and motion The velocity of the system’s center of mass does not change, as long as the system is closed. The system moves as if all the mass is concentrated at a single point. However, the center of mass itself does not rotate; instead it will make a parabolic path, as if it was a point particle.

## How do u calculate mass?

Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

## What is the center of gravity answer?

The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human’s center of gravity can change as he takes on different positions, but in many other objects, it’s a fixed location.

## What is meant by Centre of gravity?

Centre of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated.

## What is centroid formula?

The centroid is the intersection of the three medians. The three medians also divide the triangle into six triangles, each of which have the same area. The centroid divides each median into two parts, which are always in the ratio 2:1. A B 2 + B C 2 + C A 2 = 3 ( G A 2 + G B 2 + G C 2 ) .

## What is the Centre of a triangle?

In geometry, a triangle center (or triangle centre) is a point in the plane that is in some sense a center of a triangle akin to the centers of squares and circles, that is, a point that is in the middle of the figure by some measure.

## What is the Centre of mass of an equilateral triangle?

In geometry, the equilateral triangle is a triangle in which all the three sides are equal. In an equilateral triangle, the centroid and centre of mass are the same. The centroid or centre of mass of an equilateral triangle is the point at which its medians meet.

## What is the use of Centre of mass?

The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics.
