Center of Mass for Particles. The center of mass is the point at which all the mass can be considered to be "concentrated" for the purpose of calculating the "first moment", i.e., mass times distance. For two masses this distance is calculated from . For the more general collection of N particles this becomes. and when extended to three dimensions:

Two objects that have equal masses head toward one another at equal speeds and then stick together. Their total internal kinetic energy is initially 1 2 m v 2 + 1 2 m v 2 = m v 2 1 2 m v 2 + 1 2 m v 2 = m v 2. The two objects come to rest after sticking together, conserving momentum.

even though mass and weight are not the same, your weight is uniquely determined by your mass, so you can compare weights by comparing masses – if object B has twice the mass as object A, it also weights twice as much. A mass of 1 kg has a weight of mg (1 kg) (10 m/s2) = 10 N.

Sep 12, 2001 · The rest-mass of an object is numerically equal to its Newtonian inertial mass, though arguably the symbol \(m\) (or the corresponding term “mass”) has different meanings in Newtonian and relativistic physics (see, e.g., Kuhn 1962, p. 101 ff. and Torretti 1990, p. 65 ff.).

Two massless springs, of spring contacts k1 and k2, are hung from a horizontal support. A block of weight 12 N is suspended from the pair of springs, as shown above. When the block is in equilibrium, each spring is stretched an additional 24 cm. Thus, the equivalent spring constant of the two-spring system is 12 N / 24 cm = 0.5 N/cm.

The center of mass of the two masses of size M does not move. The unbalanced extra mass m accelerates downward at value a. So the spring balance reading, S, is an amount ma less than in the static case, ie. S = (2M+m)g - ma. This reduces to . S = 4M(M+m)g/(2M+m).For the total mass: F = (M + m 1 + m 2)a For the masses individually: m 1 a = T, m 2 g = T --> a = m 2 g/m 1. F = (M + m 1 + m 2)m 2 g/m 1. Problem: Near the surface of Earth, two masses, m 1 = 1 kg and m 2 = 3 kg, are connected by a string of negligible mass. The masses hang on opposite sides of a pulley with radius R.
