Question
hook question: 1.10 newtons second law of motion 1. which was easier to push: the empty cart or the full cart? why do you think so? answer:
According to Newton's second law of motion ($F = ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration), for a given acceleration, a smaller - mass object requires less force. The empty cart has less mass than the full cart, so it is easier to push as it requires less force to achieve the same acceleration.

The empty cart was easier to push because it has less mass. According to Newton's second law ($F = ma$), less force is needed to accelerate an object with less mass.
