Question

What is momentum in simple words ? Can you give an example and explain ?

Answer 1

Momentum is the quantity of motion of a moving body. In a basic sense, the more momentum a moving object has, the harder it is to stop

example
A karate player break a pile of tiles or a slab of ice with a single blow of his hand. This is because a karate player strikes the pile of tiles or the slab of ice with his hand very very fast. In doing so, the large momentum of the fast moving hand is reduced to zero in a very, very short time. This exerts a very large force on the pile of tiles or the ice slab which is sufficient to break them apart.
