Question

The definition of impulse says impulse is the integral of a force over time. Since force is a vector, impulse μst be a:

a) Scalar
b) Vector
c) Tensor
d) Matrix

Answer 1

Impulse is a vector quantity because it is the integral of force, which is a vector, over time.

Step-by-step explanation:

The impulse is defined as the integral of a force over time, which implies that it incorporates both magnitude and direction since force is a vector quantity. Consequently, because impulse is the integration of a vector quantity over a scalar (time), impulse itself must be a vector. In physics, a vector is anything that has both magnitude and direction. The impulse vector has the same direction as the force vector and its magnitude is the product of the force magnitude and the duration of its application. Just as force is a vector quantity, so is impulse. This corresponds to the fact that momentum, which impulse changes, is also a vector quantity. The answer to the question is b) Vector.
