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.

The product of the mass times the velocity of an object.

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"

What happens when the Flash jacks off, and then lets go, resulting in the skin to continue moving on its own.
Wonder Woman needs to be careful when the Flash has momentum going, before she slips.

Oh no, that figure-skater can't stop, she has too much momentum!
