Practice Reading: Multiple Choice, Single Answer ID: #4378 Gravity
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Isaac Newton was the first person to describe gravity, and he is said to have had a revelation about its existence after seeing an apple fall from a tree. He surmised from this that any object exerts a force on another object; the more massive the objects are, the greater the force of attraction between them. According to this theory, the Earth and the apple are both pulling each other together. However, because the mass of the planet is so much greater, it takes a lot more force to move it a significant distance. The apple has a tiny mass in comparison, and is easily pulled towards the Earth.

Option 1: "It pulls all objects towards each other."

Explanation: The text states that any object exerts a force on another object, indicating that gravity pulls all objects towards each other. This aligns with Newton's description of gravity as a force of attraction between masses, supporting the idea that gravity acts universally on all objects.

Option 2: "It is an electromagnetic force in the universe."

Explanation: This option is incorrect because the text specifically describes gravity as a force of attraction between masses, not as an electromagnetic force. Electromagnetic forces are distinct from gravitational forces, which are based on mass rather than charge.

Option 3: "The bigger something is, the faster it will fall."

Explanation: This statement is misleading. The text does not claim that size affects the speed of falling; rather, it explains that while larger masses exert a greater force, the speed of falling is not directly related to size but rather to gravitational force and resistance.

Option 4: "Attraction between objects causes it, altering their mass."

Explanation: This option is incorrect because the text explains that gravity is a force of attraction between objects, but it does not state that this attraction alters their mass. Mass remains constant regardless of gravitational attraction, making this statement misleading.
