The measure of the difficulty to bring a moving body to a halt.

The momentum of the body is equal to the product of the mass and the velocity of that body:

p = mv (where p and v are vectors)

Where (SI units used):
p is the momentum in Newton seconds (Ns or sec Newtons, sN)
m is the mass of the body in kilograms (kg)
v is the velocity of the body in metres per second (ms^-1)
1. A truck coming towards you at 100 ms^-1 will be hard to stop with your body because it has a lot of momentum.

2. A tenis ball thrown at you at .5 ms^-1 will be pretty easy to stop with your face because it has little momentum.

Momentum = Motion in Mass.
He has always been known as a straight A's guy. She is going to have a Physics exam upcoming weeks. She asks him to come over and tutor her..

Girl: I have trouble understand the concept of "Momentum" and how it works. Can you help me...?

Guy: Sure! It's pretty easy. P = m•v whereas P is momentum, defined by M (Mass) and V (Velocity). In another word, momentum is "mass in motion".

Girl: Can you give me an example..?

Guy: Sure...

Girl: Yes..? Why are you blushing? Do you have a fever? Are you alright? Do you need a cup of water or something..?

Guy: .. Can you come here? I will show you an example that you are asking for..

Don't you love physics? It's the fundamental of many things..

The word you're thinking of is "memento", which is a reminder of past events.
You: "I think I'll keep this as a momentum"

Me: "sigh"
