Question

Почему импульс это векторная величина ? помогите плиз!!!

Answer 1

Физ. величина равная произведению массы тела на скорость его движения называется импульсом тела. Импульс тела - векторная величина. Измерением импульса в СИ является кг - метр в сек.

Answer 2

Impulse as a Vector Quantity

Impulse is defined as the change in momentum of an object. Momentum is a vector quantity that depends on both the mass and velocity of an object. Since impulse is directly related to momentum, it is also a vector quantity.

Impulse (J) is given by the equation:

J = Δp

where Δp represents the change in momentum.

To understand why impulse is a vector quantity, let's consider the definition of momentum. Momentum (p) is given by the equation:

p = m * v

where m is the mass of the object and v is its velocity.

Since both mass and velocity are vector quantities, momentum is also a vector quantity. Therefore, any change in momentum, which is impulse, will also be a vector quantity.

The direction of the impulse vector is the same as the direction of the change in momentum. If an object experiences a change in momentum in a particular direction, the impulse vector will also point in that direction.

In summary, impulse is a vector quantity because it is directly related to the change in momentum, which is itself a vector quantity. The direction of the impulse vector is the same as the direction of the change in momentum.

I hope this explanation helps! Let me know if you have any further questions.
