Question

which of the following is an example of newtons third law of motion? a a ball rolling down a hill, with balanced forces b a person pushing against a wall, and the wall pushing back with an equal force in the opposite direction c a plane moving on a table with unbalanced forces before moving in the opposite direction 6 of 20

Explanation:

Newton's third - law states that for every action, there is an equal and opposite reaction. A person pushing against a wall and the wall pushing back with an equal force in the opposite direction is an example of this law. The other options do not represent Newton's third - law. A ball rolling down a hill with balanced forces is related to Newton's first law (inertia), and a plane moving on a table with unbalanced forces before moving in the opposite direction is more related to Newton's second law (force = mass x acceleration).

Answer:

B. A person pushing against a wall and the wall pushing back with an equal force in the opposite direction
