Questions and Answers

Newton's contemplation of the falling apple primarily led him to investigate which fundamental aspect of physics?

The properties of electricity and magnetism.
The universal force of gravity and its effects on celestial bodies. (correct)
The laws of thermodynamics and energy conservation.
The nature of light and its spectrum.

What key assumption did Newton make about the 'drawing power' of matter in relation to the Earth?

It is concentrated at the Earth's magnetic poles.
It originates from multiple points beneath the Earth's crust.
It is concentrated at the Earth's center. (correct)
It is evenly distributed across the Earth's surface.

How does Newton's insight about the apple falling 'perpendicularly to the ground' challenge prevailing scientific thought at the time?

It contradicted the belief that terrestrial and celestial phenomena were governed by separate sets of rules. (correct)
It questioned the existing understanding of projectile motion and trajectory calculation.
It reinforced the Aristotelian view of natural motion as an inherent property of objects.
It supported the idea that objects fall at varying angles depending on their composition.

What broader implication can be inferred from Newton's contemplation regarding the 'drawing power in matter'?

All matter possesses an inherent ability to attract other matter, regardless of size or composition. (B) Signup and view all the answers

Based on Newton's quote, what is the most likely reason the apple falls 'perpendicularly' to the ground, rather than at an angle?

The sum of the Earth's 'drawing power' acts directly towards the Earth's center, pulling the apple straight down. (C) Signup and view all the answers
