examples of momentum in our daily
Answers
Explanation:
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.
Hope it well help you
Answer:
stop. In physics, momentum is a quantity that can be calculated by multiplying the mass and velocity of the object involved. Momentum is expressed by the letter p. So momentum equals mass times velocity or p = m x v. Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero.
Examples of Momentum:
1. A semi-truck full of logs has a large mass and must slow down long before a stop light because even with a small velocity, it has a large momentum and is difficult to stop.
2. A four-wheeler moving at a relatively fast velocity has a smaller momentum than the semi-truck because of its small mass and will stop much faster.
3. A bullet, although small in mass, has a large momentum because of an extremely large velocity.
4. A 1000 kg car moving at 15 m/sec has a momentum of 15,000 kg•m/sec as a result of multiplying the mass and the velocity.
5. A karate expert can generate enough speed with his fist that the momentum can carry through several bricks breaking them.
6. Two football players of equal mass are traveling towards each other, one is moving at 5 m/sec and the other at 8 m/sec. The one moving with the faster velocity has a greater momentum and will knock the other one backwards.
