The notion of momentum , which derives from the Latin word Impĕtus, has several uses. The term can be used as a synonym for impulse : the force - physical or symbolic - that makes something move .
By extension, it is known as impetus to vehemence , the Energy or the verve . For example: "Thanks to the momentum of its captain, the visiting team managed to shorten the distances", “A race driver must know how to control his momentum so as not to perform risky maneuvers”, “The momentum of young people is helping to move this neighborhood forward”.
Take the case of a group of teenagers who are trying to gather money to solve your end of study trip (also called graduate trip ). The lack of support causes many of the young people to be discouraged, but others show their momentum and keep trying to raise funds. In this way those who have greater momentum go house by house and business by business trying to sell raffles, food and other products.
The idea of momentum can also refer to the amount of movement . Also called momentum or linear momentum , in this context the momentum is a physical vector magnitude that refers to the movement made by a body.
For classical mechanics, the impetus is the product of the mass of an item and his speed In a certain moment. Thus, the amount of movement of a body of 50 kilograms that reaches a speed of 100 kilometers per hour is 5,000 kg km / h. When two bodies move at the same speed, the one with the greatest mass has more momentum.
