Discuss the trajectory of the motion of the centre of mass of fire cracker that explodes in air.
When a firecracker explodes in the air, its center of mass follows the same trajectory as if no explosion had occurred. The explanation for that lies in the conservation of momentum and the dependence of the motion of the center of mass on external forces such as gravity. In that sense, before the eRead more
When a firecracker explodes in the air, its center of mass follows the same trajectory as if no explosion had occurred. The explanation for that lies in the conservation of momentum and the dependence of the motion of the center of mass on external forces such as gravity. In that sense, before the explosion, the firecracker travels through space like any other projectile along a parabolic path. During and after the explosion, the fragments exert internal forces on one another but do not influence the center of mass. Therefore, the center of mass follows the same parabolic path determined by the initial velocity and gravitational force.

A rigid body is an idealized object whose size and shape are unaffected by external forces. Particles that make up the rigid body can be moving under the effects of external forces, but the relative positions of the particles are preserved.

A rigid body is an idealized object whose size and shape are unaffected by external forces. Particles that make up the rigid body can be moving under the effects of external forces, but the relative positions of the particles are preserved. A rigid body does not deform; therefore, all the particles of it have the same displacement as the body moves. Similarly, when the rigid body rotates, each particle passes through the same angle about the axis of rotation. While perfect rigidity is impossible, materials such as steel or glass can be approximated as rigid under moderate forces. This simplifies the analysis in physics by assuming no structural deformation under typical conditions.
