Lecture 1 Centre Of Mass System Of N Discrete Particles Youtube Figure 10.5 shows two objects, labeled a and b. by definition, the center of mass of the system is found by integrating the position vector over all of the mass in the system. since the system is made of two objects, the total integral is just the sum of two separate integrals, one for each object. . = cm ∫. Center of mass definition. consider a body consisting of large number of particles whose mass is equal to the total mass of all the particles. when such a body undergoes a translational motion the displacement is produced in each and every particle of the body with respect to their original position. In this system of two particles d can be written as: d = m 1 d 1 m 2 d 2 m 1 m 2. from the equation d, can be taken as the mass weighted mean of d1 and d2. now, let us presume that the particles in the system have equal masses. hence, m 1 =m 2 = m, in this case, d = (md 1 md 2) 2m = m (d 1 d 2) 2m. The center of mass (cm) of the system is defined by the following position vector: where m is the total mass of all the particles. this vector locates a point in space — it may or may not be the position of any of the particles. it is the mass weighted average position of the particles, being nearer to the more massive particles. ∼1023 m i r i.

The radius of earth is 6.37 × 10 6 m, so the center of mass of the earth moon system is (6.37 − 4.64) × 10 6 m = 1.73 × 10 6 m = 1730 km (roughly 1080 miles) below the surface of earth. the location of the center of mass is shown (not to scale). check your understanding 9.11. suppose we included the sun in the system. Definition. the center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors relative to this point sum to zero. in analogy to statistics, the center of mass is the mean location of a distribution of mass in space.
