Volleyball
When you are serving overhand the ball will go straight over your head until the outside force (your hand) will act upon the volleyball making it go over the net.
Dusting of a cloak:
The cloak is dusted with a stick. The cloak moves forward due to motion but the dust particles embedded in the cloak fall to the ground.This is because the dust particles are still in an inertia of rest.When the cloak moves forward, they fall down.
Jumping down from a moving bus:
[When you jump down from a moving bus u tend to fall forward] This because when you jump down from a bus and touch the ground, the lower part of your body touches the ground and it comes to rest, while the upper part of your body is still in motion.You fall forward because your upper portion of your body moves forward by virtue of its inertia of motion.
Flicking card trick:
[A coin is kept over a card and the card is kept over the glass. The card is flicked away quickly and the coin falls through into the glass] This is because when the card is flicked it gains and inertia of motion but the coin is still in the inertia of rest and falls through.
No it does not. It represents momentum.
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
law of conservation of momentum
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.
An object's momentum is affected by its mass and velocity. The momentum of an object increases as either its mass or velocity increases.
The momentum of an object is determined by its mass and velocity. Momentum is calculated by multiplying an object's mass by its velocity.
The mass and velocity of an object are two factors that affect its momentum. An object with higher mass or greater velocity will have greater momentum.
The momentum of an object is affected by its mass and velocity. Momentum is directly proportional to both mass and velocity, so an increase in either will result in an increase in momentum, and vice versa.
-- mass -- velocity
To increase the momentum of an object, you can either increase the object's mass or increase its velocity. Momentum is calculated as the product of mass and velocity, so changing either factor will impact the overall momentum of the object.
Momentum = mass x velocity. Therefore, other things (velocity) being equal, momentum is directly proportional to the mass, i.e., more mass --> more momentum.
electrons that orbit the nucleus of an atom never lose momentum because of the CENTREPETAL FORCE afford by the moving electron. In our Universe, when you get to things the size of an atom, the rules for how things operate changes from what we are used to. For starters, you can no longer say that an electron acutually HAS a momentum or even a position. Instead, you can only state (1) the probability that an electron has a specific momentum or position and (2) the AVERAGE momentum or position of an electron. And it is NOT the case that we lack the ability to measure these things, or that the electron "knows" these things but we don't -- the momentum and position of electrons are inherently UN-KNOWABLE, even to the electron itself! Thus, we can not say an electron "loses" its momentum over time, because we can't even say what its momentum IS. And we can't do so because the ELECTRON ITSELF doesn't "know" its own momentum! Confusing? Don't like this? Sorry -- that's how our Universe operates.

It relates to work in the sense that work involves moving things, which involves changing their momentum, and to change momentum you have to create an equal and opposite momentum so that momentum is conserved - although the planet Earth is such a convenient momentum sink that in most cases this happens without being specifically noticed.
