Momentum is the variation of the amount of movement<\/a> or linear momentum.<\/p>\n

\"Impulso\"<\/p>\n

MOMENTUM FORMULA AND AMOUNT OF MOTION<\/h2>\n

If we consider a mass that remains constant in time under the action of a constant force, the quantity of motion is the product of the velocity (v<\/strong>) and the mass (m<\/strong>). According to the\u00a0Newton's second law<\/a>if to a mass\u00a0m<\/strong>\u00a0a force is applied\u00a0F<\/strong>\u00a0The latter acquires an acceleration\u00a0a<\/strong>according to the expression:<\/p>\n

F<\/strong>=ma\u00a0<\/strong><\/span><\/p>\n

multiplying both members by the time\"{\\displaystyle<\/span>\u00a0where the designated force is applied:<\/p>\n

F<\/strong>\u0394t = ma<\/strong>\u0394t \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0<\/span><\/p>\n

Like a<\/strong>\u0394t = \u0394v<\/strong>we have:<\/p>\n

F<\/strong>\u0394t = m\u0394t = m\u0394v<\/strong>\u00a0 \u00a0\u00a0<\/span><\/p>\n

and finally:<\/p>\n

I<\/strong>=F<\/strong>\u0394t\u00a0<\/span><\/p>\n<\/blockquote>\n

Momentum is the force per time variation. It is also represented as the change in the amount of motion.<\/p>\n

AMOUNT OF MOVEMENT<\/h3>\n

The quantity of motion is defined as the mass times the change in velocity. It is used to differentiate between 2 bodies with the same velocity but different mass.<\/p>\n

p=m\u0394v<\/strong><\/span><\/p>\n

The momentum applied to a body is also equal to the change in the amount of motion, so another way to calculate the momentum is:<\/p>\n

I=\u0394p<\/span><\/p>\n

Equating the 2 formulas for calculating momentum, it can be said that the force per time variation will be equal to the mass per velocity variation.<\/p>\n

F<\/strong>\u0394t = m\u0394t = m\u0394v<\/strong>\u00a0 \u00a0\u00a0<\/span><\/p>\n

IMPULSE APPLICATIONS<\/h2>\n

Momentum is very important as soon as the variable time variation. <\/strong>This explains that by applying a force in a very small interval, achieving a variation of movement, the equivalent force becomes almost infinite. This is applicable to the dry strokes, to making a jump, ..., these are situations that only work if the time in which the force is applied is very small.<\/p>\n

IMPULSE CONFUSED WITH NEWTON'S FIRST LAW<\/h2>\n

Sometimes this momentum force is confused with Newton's first law. Here are some examples<\/p>\n
