Every body has a point where its whole mass is concentrated so we can lift any body, by applying force on that point only.

Center of Mass (COM) is a point where whole body's mass is assumed to be concentrated.

If there are two masses m_{1} and m_{2} separated by distances x_{1} and x_{2} from a fixed point. The Center of mass (X) is given by

If there are masses m_{1}, m_{2},.....m_{n} having distances x_{1}, x_{2},......x_{n} then the Center of mass (X) is given by

Given: Mass m

Mass m

Distance x

Distance x

The Center of mass formula is given by X = $\frac{m_{1} x_{1} + m_{2} x_{2}}{m_{1} + m_{2}}$

= $\frac{2 \times 0 + 3 \times 5}{2 + 3}$

= $\frac{15}{5}$

= 3 cm.

Given: Masses m

Distances x

The Center of mass is given by X = $\frac{m_{1} x_{1} + m_{2} x_{2} + m_{3} x_{3}}{m_{1} + m_{2} + m_{3}}$

= $\frac{7 \times 5 + 4 \times 6 + 3 \times 8}{5 + 6 + 8}$

= 4.368 cm

= 0.044 m.
