You can’t feel the force of attraction between Mars because the gravitational force is too weak to be perceptible with our senses. The force of gravity depends on the mass and distance between objects, and while Mars has a gravitational pull, it is not strong enough to be physically noticeable.
Comprehensive answer to the question
The force of attraction between Mars and an object on Earth cannot be felt because it is simply too weak to be perceptible to our senses. The gravitational force between two objects depends on their mass and the distance between them. In the case of Mars, while it does indeed have a gravitational pull, it is not strong enough to be physically noticeable.
To provide a more detailed explanation, let’s delve into the concept of gravity. Gravity is the force of attraction that exists between any two objects with mass. It is responsible for keeping objects grounded on Earth, and it governs the motion of celestial bodies like planets and moons. The strength of the gravitational force depends on the masses of the objects involved and the distance between them. The greater the mass of an object, the stronger its gravitational force.
Mars is significantly smaller than Earth, with roughly one-tenth the mass of our planet. This difference in mass means that Mars has a weaker gravitational force compared to Earth. Additionally, since the force of gravity weakens with distance, the fact that Mars is much farther away from us than, for example, the Earth’s own moon, further diminishes the perceived force of attraction.
To put things into perspective, here’s a quote from Isaac Newton, the renowned physicist who laid the foundations of classical mechanics, including his famous law of universal gravitation:
“I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.”
- Isaac Newton
This quote reminds us that while the force of gravity has been quantified and described, its underlying cause or mechanism is still a topic of ongoing scientific investigation.
Interesting facts about Mars and gravity:
- Mars has only about 38% of the gravity found on Earth. This means that if you were on Mars, objects would weigh less there compared to their weight on Earth.
- The force of gravity on Mars is sufficient to hold onto an atmosphere, although it is much thinner than Earth’s atmosphere.
- Due to its weaker gravity, Mars has a lower escape velocity compared to Earth. This means that it is easier for objects (such as spacecraft) to escape Mars’ gravitational pull and travel into space.
- Mars’ gravity has been studied extensively by various space missions, including NASA’s Mars Science Laboratory and the ongoing Mars Perseverance rover mission.
While we cannot physically feel the force of attraction between Mars and us, the study of gravity and its effects on celestial bodies continues to captivate scientists and drive our exploration of the universe.

This video discusses the uncertainty in Newton’s law of gravitation at different distances. It explains that the law is only accurate at certain distances, and that we don’t know whether it applies at smaller distances. This uncertainty means that we don’t know how strong gravity is at different scales, and that there are many potential truths about the universe that we haven’t discovered yet.
Some additional responses to your inquiry
1. Why can you not feel a force of attraction between you and the planet Mars? Because it’s too far away – gravity decreases with distance.
You cannot feel a force of attraction between you and the planet Mars because the distance is too great and the gravitational force is inversely proportional to the square of the distance.
Because, in physics there is inverse proportionality between the gravitational force and the radius of the distance and that is the reason why option D is correct.
The distance is too great for the attraction to make a difference
