### Definitions?

So in class today, we discussed about De Broglie's equation, but what is momentum? I understand that it has the unit and variable for itself but can anyone explain what does momentum really is?

Momentum is the inertia of a moving object. Just like a stationary heavier object has more inertia (the tendency of an object to stay or move in the same way as it has been), an moving object that is heavier or is moving faster has more momentum, thus p=mv.

Momentum is measured as mass times velocity and in physics it can be looked at as the quantity of motion of a moving object. If an object has a mass and it is moving (in motion), then it will have momentum. According to p=mv, we can know that momentum is directly proportional to the object's mass and its velocity.
