The linear momentump of a particle of mass m moving at a velocity v is defined to be the product of m and v: (6-15)p=mv Because the product of m and v is the product of a scalar and a vector quantity, p is a vector quantity. Further, the direction of the momentum p is the...
The meaning of LINEAR MOMENTUM is the momentum of translation being a vector quantity in classical physics equal to the product of the mass and the velocity of the center of mass.
Also, energy is a scalar, and momentum is a vector. Linear Momentum and Newton's Second Law Though Newton's second law is commonly stated as F = ma, Newton actually stated the net force on an object is the time rate of change of the momentum, which can be mathematically stated as: ...
Momentum is a vector quantity, but kinetic energy is a scalar quantity. KE has no direction associated with it. Is kinetic energy also a conserved quantity for a system if the net external force acting on that system is zero? Well, kinetic energy changes if there is net work done on a ...
Energy is scalar quantity and its conservation helps us to predict magnitude quantity (for example, speed – magnitude of the velocity of an object). The linear momentum is vector quantity. Its conservation will help us to predict not only magnitude but also the direction of an object’s motio...

Define the Cartesian stress vector in terms of the Cartesian components of the Cauchy stress tensor as (10.113)tA≔σABEB From the scalar form of the balance of linear momentum above, along with the fact that the basis vectors are everywhere constant (i.e., EA,B=0), the Cartesian vecto...

Find the magnitude of the linear momentum for a 75.0 kg athlete running with a speed of 10.0 m/s.Calculate the momentum of a 100 kg object moving with velocity 10m/s.What is the difference between momentum and impulse? Are these vector quantities or scalar quantities? Write down the ...
The challenging problem in irregular and random morphologies is to produce an analytical or numerical evaluation of the deviations in scalar or vector fields. In previous work, the authors have presented a few exact closures for predetermined regular and random porous medium morphologies. The questions...
