Question

What is the center of mass????

Answer 1

$\bold{\large{\underline{\underline{\sf{StEp\:by\:stEp\:explanation:}}}}}$

Point representing the mean position of the matter in a body or system.

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 example:-

The center of mass of a uniform disc shape would be at its center.

The center of mass can be calculated by taking the masses you are trying to find the center of mass between and multiplying them by their positions. Then, you add these together and divide that by the sum of all the individual masses.

_______________________

Center of mass:- it is the weighted average position of mass in a body or a system of particles.

Center of gravity:- It is the point in a body where the net torque due to gravitational forces is 0. Center of gravity is the point where the weight of the body acts.

NOTE:-

Center of mass of the human body depends upon the gender and position of limbs.

Answer 2

Center of Mass ;

The center of mass of a system is the unique point in which the sum of all parts of the system is zero.

• This is basically the average position in which this unique point is located.

Explanation:

The center of mass is defined as the average position of all the parts of a given system which is basically the zero point mass of the system.

• For one dimensional case of particles system, the center of mass is given by an equation

$\frac{X_{center} =m_{1} x_{1} +m_{2} x_{2} +m_{3} x_{3} }{m_{1}+m_{2}+m_{3}   }$

where,

$X_{center}$

is the center of mass of all the particles

$m_{1} m_{2} m_{3}$

are the masses of the particles
