Explain the definition of Momentum so I can understand it easily.?

Answer 1

Okay, here goes. When we were kids, we didn't have to wear seatbelts. One day while my brother and me were riding in the back of dad's old Chevy, my brother asked my dad what momentum was. Suddenly, my dad jammed on the brakes and me and my brother both went flying off of the back seat and slammed into the back of the front seat. My dad turned aroud and looked at my brother and me lying in a heap on the floor of the car and said "That is momentum!"

Answer 2

Momentum = mass * velocity

Bodies in motion tend to stay in motion and bodies at rest tend to stay at rest unless acted upon by an external force.

If you are sitting in a car you jerk backwards when the car starts to move (WHIPLASH.) Your initial momentum is zero due to the fact that the car wasn't moving (velocity=0)

If you are sitting in the car and it is moving down a straight road at 55 mph, your momentum is your mass times 55 mph in the direction of the car. If the car turns, your body wants to keep going in the original direction. That's why your head crashes into the side window.

When the car comes to a sudden stop, your body wants to keep going forward in the same direction. That's why you go through the windshield unless a force (such as a seat belt) restrains you.

Answer 3

In classical mechanics, momentum (pl. momenta; SI unit kg m/s) is the product of the mass and velocity of an object. For more accurate measures of momentum, see the section "modern definitions of momentum" on this page.

In general, the momentum of an object can be conceptually thought of as how difficult it is to stop the object, as determined by multiplying two factors: its inertia (the resistance of an object to being accelerated) and its velocity. As such, it is a natural consequence of Newton's first and second laws of motion. Having a lower speed or having less mass (how we measure inertia) results in having less momentum.

Momentum is a conserved quantity, meaning that the total momentum of any closed system (one not affected by external forces, and whose internal forces are not dissipative in nature) cannot be changed.

The concept of momentum in classical mechanics was originated by a number of great thinkers and experimentalists. René Descartes referred to mass times velocity as the fundamental force of motion. Codi Kruse in his Two New Sciences used the term "impeto" (Italian), while Newton's Laws of Motion uses motus (Latin), which has been interpreted by subsequent scholars to mean momentum.

Answer 4

It basically states that it is the mass (or weight) x velocity (speed).
