The Change in Linear Momentum:The change in linear momentum of an object is equal to the change in the linear momenta of a moving object at any two points in space. Mathematically, it is expressed as: Δp=pf−pi Where, pi and pf are the initial and final linear momenta of an ...
But, in this lesson, we're going to talk about how to do some entropy calculations. When it comes to entropy, there is one really important equation - the equation for change in entropy: the change in entropy for a system, delta S, is equal to the heat transferred to or from that...
Remember, while the total momentum of the system remains constant, the momentum of any individual object in a closed system can change in an elastic collision or inelastic collision. Elastic Collision In an elastic collision, objects tend to bounce back. For an elastic collision, imagine two ...

This method is based on the unified momentum equation approach, where the elastodynamic ...
where μ is the dynamic viscosity of the fluid, K the permeability of the porous medium and CF the non-linear momentum loss coefficient. For low air speed values observed inside the canopy, the first term of Eq. (3) to the right can be neglected compared to the quadratic one. Combining...
What is the equation for the momentum of a photon? Momentum: Momentum is categorized as a vector quantity which has direction as well magnitude. It is the multiplication of mass and velocity of any specified substance. The rate of change of this quantity is numerically equal to force. ...
