Module 12: System of Particles (Energy and Momentum) Flashcards
(14 cards)
If no external force acts on the particles of a system, the linear momentum and the angular momentum about 𝑂 of the system of particles are?
conserved
the system of the external forces
acting on the particle and the system of the effective forces of the particles are?
equipollent
The linear momentum of the system of particles and its angular momentum about the fixed point 𝑂 are?
conserved
this is often applied when particles collide or interact
the conservation of linear momentum
The system of the external forces and the system of the effective forces have the same?
resultant and moment
why are the system of the external forces acting on the particle and the system of the effective forces of the particles are equipollent?
both have the same resultant and moment
this is applicable if the sum of the external forces is zero
conservation of linear momentum
these have the same resultant and moment
- system of the external forces
- system of the effective forces
is defined as the product of its mass and acceleration
effective force of a particle
External forces and the internal forces acting on the various particles form a system
equivalent to the?
system of the effective forces
this means equivalent only when
the system of forces is acting on a set of dependent particles
equipollent
The __________________________ of particles moves as if the entire mass of the system and all the external forces were concentrated at that point
mass center of a system
The conservation of linear momentum is often applied when particles?
collide or interact
it is the sum of the kinetic energies of the various particles of the system
kinetic energy of a system of particles
