Final answer:

The correct answer is B, which states that gravity would pull both the notebook and the pencil to the ground. Their acceleration would be the same due to gravity being a consistent force on all objects, regardless of their mass, as long as there is no air resistance.

Step-by-step explanation:

If a notebook and a pencil were to fall off a table, B. Gravity would pull them to the ground. According to the principles of physics, as set forth by Galileo and later expanded upon by Einstein, all objects in a vacuum, regardless of their mass, will experience the same acceleration due to gravity. This means that, absent any air resistance, the notebook and the pencil would hit the ground at the same time. The correct answer does not suggest that the mass of the objects would be similar (A), nor that their acceleration would be different (C), and the idea that gravity would make the notebook fall sooner because it is heavier (D) is a common misconception.

Galileo's experiments demonstrated that objects, irrespective of their mass, will fall at the same rate in the absence of air resistance. This was illustrated thoughtfully with the concept of a large room falling around people at the same rate they are falling, as seen in the reference material. Einstein's postulate on the equivalence of gravity and acceleration further supports this, asserting that gravity and acceleration are indistinguishable in free fall.

Answer: b

Step-by-step explanation:

If someone showed you two spheres of the same size but with different masses, say 1g and 10kg, and asked which would hit the ground first after being dropped from the Leaning Tower of Pisa, what would you say? If you’re like most people, you would say the 10kg sphere would hit the ground first. Aristotle said so too, and for 1,000 years everyone believed him. But doing the experiment would show you, besides a great view of Pisa, that in fact, both spheres hit the ground at the same time.This is exactly what Galileo did, showing the world that objects of different masses fall at the same rate. (This is also a good example of why it is important to do experiments yourself and not to just take someone else’s word for it.) To start understanding why Galileo was right, we need to understand the difference between several physics words that are often jumbled together and confused: mass, weight, speed, velocity, acceleration, and force.
