Question

momentum
a feeling of annoyance
the force that something has when it is moving
unable to be read
able to be bent, stretched, or molded
i dont know this word.

Explanation:

"Momentum" in physics refers to the quantity of motion an object has. It is calculated as the product of an object's mass and velocity. The option "the force that something has when it is moving" is the closest to the physical definition of momentum (though more accurately it's mass times velocity, the essence is related to motion). The other options: "a feeling of annoyance" is about emotion (not relevant), "unable to be read" is about legibility (unrelated), "able to be bent, stretched, or molded" is about malleability (not momentum).

Answer:

the force that something has when it is moving
