### Linear Momentum

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

### Re: Linear Momentum

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.

### Re: Linear Momentum

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.

### Re: Linear Momentum

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

### Re: Linear Momentum

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.

### Re: Linear Momentum

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?

### Re: Linear Momentum

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
