FAQs on Gravitation Mock Test for JEE Main 2025-26: Practice & Prepare
1. What is the difference between gravity and gravitation?
Gravity refers specifically to the force of attraction exerted by the Earth (or any other celestial body) on objects near its surface, while gravitation is the universal force of attraction between any two objects that have mass. For example, gravity pulls an apple toward the Earth, but gravitation is responsible for the attraction between the Earth and the Moon.
2. State Newton's law of universal gravitation.
Newton’s law of universal gravitation states that every particle of matter attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically, F = G (m1m2) / r2, where G is the gravitational constant.
3. What is the value and SI unit of the gravitational constant G?
The universal gravitational constant (G) has a value of 6.674 × 10−11 N m2 kg−2. The SI unit of G is Newton metre2 per kilogram2 (N m2 kg−2). G measures the strength of gravitational force between two unit masses one meter apart.
4. What factors affect the force of gravitational attraction between two objects?
The force of gravitational attraction depends on:
• The masses of the two objects (directly proportional)
• The distance between their centers (inversely proportional to the square of the distance)
• The universal gravitational constant (G)
5. What is free fall?
An object is said to be in free fall when it is moving under the influence of the gravitational force of the Earth only, with all other forces such as air resistance being neglected. In free fall, all objects accelerate toward the Earth at the same rate, regardless of their mass.
6. How is acceleration due to gravity (g) calculated and what is its value on Earth?
The acceleration due to gravity is given by g = G M / R2, where M is Earth’s mass and R is Earth’s radius. On Earth, the value of g is approximately 9.8 m/s2.
7. Give an example of the gravity model used in geography or economics.
In geography, the gravity model predicts the interaction between two places based on their population sizes and distance. For example, the amount of trade between two cities is typically proportional to their populations and inversely proportional to the distance between them, similar to the principle of universal gravitation.
8. What does 'gravity of a situation' mean?
The phrase 'gravity of a situation' refers to the seriousness or importance of a particular event or issue. It is a figurative use of the word ‘gravity’ to indicate that something requires careful attention and consideration due to its weight or impact.
9. What is the difference between gravity and the gravitational constant?
Gravity is the actual force of attraction experienced by objects due to the Earth's mass, while the gravitational constant (G) is a universal value used in calculating the gravitational force between any two masses. Gravity varies with location, but G is a fixed value.
10. Why do astronauts experience weightlessness in space?
Astronauts experience weightlessness because they are in a state of free fall around the Earth. Both the spacecraft and the astronaut inside are falling toward the Earth due to gravity at the same rate, creating the sensation of being weightless.
11. Which factors can cause a variation in acceleration due to gravity at different locations on Earth?
The acceleration due to gravity (g) varies due to:
• The shape of the Earth (flatter at poles, bulged at equator)
• Altitude (higher altitudes have lower g)
• Depth (g decreases below Earth’s surface)
• Local geological formations
12. Why is gravitational force considered the weakest force in nature?
The gravitational force is considered the weakest fundamental force because it is much weaker compared to other forces like electromagnetic, strong nuclear, and weak nuclear forces. Despite its weakness, gravity has an infinite range and controls the large-scale structure of the universe.
