Question

According to the Universal Law of Gravitation, every object attracts every other object in the universe. Why can’t you feel the force of attraction between you and Mars?
A. There is no force of attraction between you and Mars.
B. Your mass is too low.
C. Mars is a larger planet than Earth.
D. Mars is a long distance away.

2 Answer

  • The correct response for why you can't feel the force of attraction between you and Mars is because D. Mars is a long distance away, and thus why there is no gravitation attraction between you and Mars.
  • The correct answer is D. Mars is a long distance away.

    Explanation:

    The gravitational force is a natural force that operates in all the universe and causes objects with less mass (amount of matter) to be attracted to those with more mass. Additionally, according to Newton's law of gravity, this phenomenon is inversely proportional to the distance between the objects. This means, the larger the distance between one object and another the less gravitational force.

    This explains why all objects in planet Earth are under the influence of the gravitational force produced by Earth that made them have an attraction to the center of the planet, but they do not feel attracted to other planets or bodies in the universe because these are a long distance away and thus, their gravitational force is low. Thus, you cannot feel the force of attraction between you and Mars because Mars is a long distance away.
