Newton's third law of motion states that for every action there is an equal and opposite reaction. Science teachers often model this

law by showing what happens when two floating balls collide in a pool of water. What is the most likely reason that science teachers

explain this law by modeling it?

A) The law is an abstract idea that may be difficult to understand without seeing how it works.

B) The objects governed by the law are too small to be easily observed directly.

C) The law does not apply to any objects found on Earth.

D) The objects governed by the law are too dangerous to be observed directly.

A) The law is an abstract idea that may be difficult to understand without seeing how it works.

Explanation:

A scientific theory is something built to fit the empirical data available in observations, and is proposed as a principle or set of principles to explain a class of phenomena. Because it is empirical and abstract, it can be difficult to understand, even by students. For this reason, it is common for teachers to look for ways to show these laws through palpable objects so that students can visualize what is happening and thus understand the purpose of the law. An example of this occurs when the teacher shows what happens when two floating balls collide in a pool of water, to explain to Newton's third law to students.

A

Explanation:

It's often hard for students to grasp an idea by just an explaination, so showing them is the best way of them actually understanding.
