Momentum in classical mechanics is defined as mass times velocity. The magnitude of the momentum of an object with mass 3000kg and speed 0.2 m/s has a momentum of 600 mkg/s. A human walking at the same speed of 0.2 m/s weighing, let's say, 100 kg has a momentum of 20 mkg/s which is 30 times smaller.
When an object is moving very fast, it has a lot of momentum, which is the product of its mass and velocity. Stopping this object requires applying a force in the opposite direction of its motion, which can be challenging due to the high momentum. Additionally, factors such as air resistance and friction can also contribute to the difficulty of stopping a fast-moving object.
An object's momentum is determined by multiplying its mass by its velocity. Mathematically, momentum (p) is expressed as: p = mass (m) x velocity (v). Momentum is a vector quantity, meaning it has both magnitude and direction.
-- Measure the weight of the marble. -- While on the same planet, measure the weight of the basketball. Since both measurements were made on the same planet, the ratio of the weights is the same as the ratio of the masses. -- Divide the big weight by the small weight (Wb/Wm); call the answer ' R '. -- Start the basketball moving, and measure its speed; call the speed ' S '. -- Make the marble move at a speed of ( R times S ). Their momenta are now equal. Momentum = (mass) times (speed), and that product is now the same for both objects.
inertia just depends on mass. Big mass=hard to move.
A big force applied for a short time causes a bigger change in momentum compared to a small force applied for a longer time. This is because momentum is the product of force and time, so a larger force produces a greater change in momentum in a shorter duration.
Momentum is speed or force of movement and it is defined as moving body. Momentum must have both mass and velocity. Examples of momentum include if a car and big truck are rolling down a hill, the truck will roll faster. A bullet has a lot of momentum with a small mass.

Momentum is the physical movement of mass m with speed v or velocity V creates momentum p =mv or p=mV. Every spec of moving mass creates momentum. This makes momentum a very big deal in physics. Momentum also creates scalar and vector energy cp and cP. Vector Momentum Energy cP is the mysterious "Dark Energy". it is mysterious because physicists define energy as a scalar and thus overlook, vector energy. The famous Tangent Vector Force F=mdV/dt is the Momentum Force dcP/dr = dcP/cdt = dP/dt = dmV/dt = mdV/dt.
Momentum is a measure of how hard it is going to be to get something to stop. Big objects going fast have lot of momentum. Getting hit by a truck will hurt more than getting hit by a fly. Momentum is worked out as mass x velocity so you need to know how fast it is going aswell as how much it weighs.
Of course! The mass controls its speed, momentum, and how it tilts as its rotation around the sun continues. As a planet rotates on its axis, it will tilt at the sun, which is a big gravity machine. The earth is believe to be tilted because of collisions that are believed to have taken place billions of years ago. The earth collided with other proto planets in space, and became tilted. - pianodriver
Inertia and Momentum in FootballInertia is a mass's resistance to changes in its momentum. Objects that have greater mass have greater inertia, so they are more difficult to move when they are at rest and more difficult to stop when they are moving. A 320-pound NFL nose-tackle has lots of inertia. A runt like me who weighs a buck fifty and change, not so much. The nose-tackle is gonna be hard to move out of the way, so blocking him will be difficult. And if a running back carrying the ball runs into him, the play might end right then and there. If he ran into me, well, let's say that he would easily overcome my inertia, knock me into next week, and take it to the house.Which brings us to momentum. Momentum is also related to mass, but it is also related to velocity. If an object is at rest, it has zero momentum. A moving object, however, has momentum. Double the speed and you double the mo. Triple the speed, triple the mo. If a running back runs fast, he will build up momentum. He can use that momentum to overcome another player's inertia. If he runs into the nose-tackle, he'll need lotsa mo to overcome his inertia. If he runs into me, he won't need much.Just to complicate this a bit, an object with momentum has kinetic energy, and energy can be used to do work. To do work you must apply a force, and it's that force that can change another object's momentum. Since mass can't change, it stands to reason that velocity must change. So when the running back picks up a head of steam and plows into me, he's gonna change my momentum in a big way. I'm gonna go flying like a little kid's rag doll.

It is 3000 kilograms.
The fat guy has momentum of his mass x velocity; when they collide acceleration ( and hence force) is applied when they stop. The slim guy has momentum of his mass x velocity and stop. The same acceleration occurs when they collide and stop but the force he applies is much smaller (Force = mass x acceleration). So he falls down from the force of the big guy and the big guy does not feel much.
