Question

which of the following is an example of newtons second law of motion? a a rocket launching into space b a person pushing a heavy box across the floor c a soccer ball rolling down a hill newtons laws! - checkpoint review #1! by jkosen 6th grade 7th grade 8th grade newtons laws of motion physics

Explanation:

Newton's second law states that force equals mass times acceleration ($F = ma$). When a person pushes a heavy box across the floor, a force is applied to the box (mass), and it accelerates according to the law. A rocket launching is more related to Newton's third - law (action - reaction). A soccer ball rolling down a hill is mainly due to gravity and friction, not a direct example of applying a force to cause acceleration as in pushing a box.

Answer:

B. A person pushing a heavy box across the floor
