Show that in the absence of any external force, the velocity of the centre of mass remains constant.
To show that the velocity of the center of mass is constant when there are no external forces, we start with the definition of the center of mass in terms of masses and positions of particles in a system. By taking the derivative of this position, we see that the velocity of the center of mass is aRead more
To show that the velocity of the center of mass is constant when there are no external forces, we start with the definition of the center of mass in terms of masses and positions of particles in a system. By taking the derivative of this position, we see that the velocity of the center of mass is a weighted average of the individual particle velocities.

State the factors on which the position of the centre of mass of a rigid body depends.
The position of the center of mass in the rigid body depends on several factors. One of these includes the distribution of mass within the object. Thus, an object of uniformly distributed mass has a center of mass at its geometric center, while an unevenly distributed mass has a center nearer to theRead more
The position of the center of mass in the rigid body depends on several factors. One of these includes the distribution of mass within the object. Thus, an object of uniformly distributed mass has a center of mass at its geometric center, while an unevenly distributed mass has a center nearer to the heavier region. The shape of the body is also involved in this; symmetrical shapes have their center of mass at the center of symmetry, while asymmetrical shapes have it offset from that point. Disturbance in density would further shift the positions of the center of mass toward denser regions. For systems of bodies, further external forces or constraints can affect its position.

What is meant by a particle, a system and internal and external forces?
A particle is an idealized small-sized object with mass but negligible in size, and used in physics to simplify the problems by taking the objects as point masses. The system means a collection of particles or objects that are taken for analysis, and it may be isolated from the external influences oRead more
A particle is an idealized small-sized object with mass but negligible in size, and used in physics to simplify the problems by taking the objects as point masses. The system means a collection of particles or objects that are taken for analysis, and it may be isolated from the external influences or open to them. The forces exerted by the particles inside a system on each other do not affect the total momentum of the system, hence termed internal forces. In contrast, external forces act on the system from outside its boundaries, changing its momentum and influencing its overall motion. Understanding these concepts is essential for analyzing physical interactions and dynamics.
