What is linear momentum and how do we solve for it?

Linear momentum is the product of the mass and velocity of an object. It is a vector quantity with units of kg*m/s, and is conserved.

Linear momentum, p, can be calculated by multiplying the mass of an object, m, by its velocity, v. p = mv. We can use (the uncertainty of) this value in Heisenberg's Indeterminacy Equation.

Linear momentum is p, where its formula is composed of p=mv or Momentum = Mass (usually kg) * Velocity (usually m/s).

Linear momentum is mass x velocity, but if you're looking for what that means, it's basically a measure of how hard it is to stop something that's already moving. Higher linear momentum = harder to stop the object.

How does linear momentum relate to the De Broglie equation? I know the equation shows that wavelength = planck's constant / momentum, but what exactly does this mean? Does it just mean that an object with higher momentum will have a shorter wavelength? Cause it shows an inversely proportional relationship between these 2 variables. Does it work for only particle property objects or does it work for wavelike property objects too?

You somewhat answered your own question. Linear momentum relates to the de broglie equation in that it has an inverse relationship with wavelength. So yes a larger momentum means a smaller wavelength. For example a car moving 60 mph has a much larger momentum then an electron, so it has a much smaller wavelength
