Gravitation
Gravitation is a fundamental force of nature that governs the motion of objects with mass. It is responsible for the attraction between two objects and plays a crucial role in the behavior of celestial bodies, such as planets, stars, and galaxies.
Here are some key points to understand about Gravitation:
- Law of Universal Gravitation: This law, formulated by Sir Isaac Newton, states that every particle in the universe 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 them. The formula for calculating the gravitational force (F) between two objects is given by:F = G * (m1 * m2) / r^2Where: F is the gravitational force G is the gravitational constant (approximately 6.67430 × 10^(-11) Nm^2/kg^2) m1 and m2 are the masses of the two objects r is the distance between the centers of the two objects
- Gravitational Field: A gravitational field is the region in which an object with mass experiences a force due to the presence of another object. The gravitational field strength at a given point is the force experienced per unit mass placed at that point. Near the Earth’s surface, the gravitational field strength is often denoted as ‘g’ and has an approximate value of 9.8 m/s².
- Acceleration Due to Gravity: The acceleration experienced by an object in a gravitational field is called the acceleration due to gravity. It represents the rate at which the object’s velocity changes under the influence of gravity alone. Near the Earth’s surface, the acceleration due to gravity is approximately 9.8 m/s².
- Gravitational Potential Energy: The gravitational potential energy of an object is the energy associated with its position in a gravitational field. It is the work done in moving the object from a reference point (usually taken as infinity) to its current position, against the force of gravity. The gravitational potential energy (PE) of an object of mass (m) at a height (h) above the reference point is given by:PE = m * g * hWhere: PE is the gravitational potential energy m is the mass of the object g is the acceleration due to gravity h is the height above the reference point
These concepts of Gravitation are essential not only for understanding the behavior of objects on Earth but also for comprehending the motion of celestial bodies and phenomena in the universe.
The syllabus for the NEET Chemistry section does not specifically include the topic of Gravitation. Gravitation is primarily a topic covered in the Physics section of the NEET syllabus. However, I can provide you with a brief overview of the concept of Gravitation.

How is Required NEET-CHEMISTRY-SYLLABUS Gravitation
Gravitation is an important concept in physics that describes the force of attraction between objects with mass. It is governed by Newton’s law of universal gravitation, which states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Here are some key aspects related to the concept of Gravitation:
- Law of Universal Gravitation: This law, formulated by Sir Isaac Newton, states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The equation for calculating the gravitational force (F) is:F = G * (m1 * m2) / r^2where F is the gravitational force, G is the gravitational constant (approximately 6.67430 × 10^(-11) Nm^2/kg^2), m1 and m2 are the masses of the objects, and r is the distance between their centers.
- Gravitational Field: A gravitational field is a region in which an object experiences a force due to the presence of another object. The gravitational field strength at a point is defined as the force experienced per unit mass placed at that point. The acceleration due to gravity (g) is a measure of the gravitational field strength and is approximately 9.8 m/s² near the Earth’s surface.
- Acceleration Due to Gravity: The acceleration due to gravity is the acceleration experienced by an object in a gravitational field. Near the Earth’s surface, the acceleration due to gravity is denoted by ‘g’ and has an approximate value of 9.8 m/s². This value varies slightly with location and altitude on Earth.
- Orbital Motion: Gravitation plays a significant role in the orbital motion of celestial bodies. The motion of planets, moons, satellites, and other objects around a central body is governed by the gravitational force acting between them.
- Kepler’s Laws: Kepler’s laws describe the motion of planets around the Sun. These laws include the law of orbits, which states that planets move in elliptical orbits with the Sun at one of the foci; the law of areas, which states that planets sweep out equal areas in equal times; and the law of periods, which states that the square of the orbital period of a planet is proportional to the cube of its average distance from the Sun.
Understanding Gravitation is essential for comprehending various phenomena in the universe, such as the motion of celestial bodies, satellite systems, and the behavior of objects under the influence of gravity.
Case Study on NEET-CHEMISTRY-SYLLABUS Gravitation
Certainly! Let’s consider a case study on the application of gravitation.
Case Study: Orbital Motion of Satellites
In this case study, we will examine the orbital motion of satellites around the Earth, which is governed by the principles of gravitation.
Overview: Satellites are artificial objects placed in orbit around celestial bodies, such as the Earth, for various purposes like communication, weather monitoring, navigation, and scientific research. The motion of satellites is determined by the gravitational force between the satellite and the Earth.
Key Concepts:
- Gravitational Force: According to Newton’s law of universal gravitation, the force of attraction between the satellite and the Earth is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- Centripetal Force: The gravitational force acts as the centripetal force that keeps the satellite in its orbit. It provides the necessary inward force to balance the satellite’s tendency to move in a straight line due to its inertia.
- Orbital Velocity: The satellite’s orbital velocity is the minimum velocity required for it to maintain a stable orbit around the Earth. It depends on the mass of the Earth, the radius of the orbit, and the gravitational constant.
- Escape Velocity: Escape velocity is the minimum velocity required for an object to escape the gravitational pull of a celestial body. It depends on the mass of the celestial body and the distance from its center.
Case Study Scenario: Let’s consider a communication satellite placed in a circular orbit around the Earth.
Given: Mass of the Earth (M) = 5.97 × 10^24 kg Radius of the Earth (R) = 6.37 × 10^6 m
Objective: Calculate the orbital velocity of the satellite and determine whether it has sufficient velocity to remain in a stable orbit or escape Earth’s gravitational pull.
Solution: To calculate the orbital velocity (v) of the satellite, we can use the following formula:
v = √(G * M / r)
where G is the gravitational constant and r is the distance between the satellite and the center of the Earth (radius of the orbit).
Let’s assume the satellite is placed in a geostationary orbit, which is approximately 35,786 km above the Earth’s surface (R + altitude of the orbit).
Altitude of the orbit = 35,786 km = 35,786,000 m Radius of the orbit (r) = R + altitude of the orbit
Substituting the given values into the formula:
v = √((6.67430 × 10^(-11) Nm^2/kg^2) * (5.97 × 10^24 kg) / (6.37 × 10^6 m + 35,786,000 m))
After calculating, we find the orbital velocity (v) of the satellite.
Once we obtain the orbital velocity, we can compare it with the escape velocity to determine whether the satellite can remain in orbit or escape the Earth’s gravitational pull. If the orbital velocity is less than the escape velocity, the satellite will remain in orbit; if it is greater, the satellite will escape.
Discussion: The case study highlights the application of gravitation in understanding the orbital motion of satellites. The calculations involving the gravitational force and the determination of orbital velocity and escape velocity help ensure that satellites are placed in stable orbits for their intended purposes.
Keep in mind that this case study is a simplified example, and real-world scenarios involve more complexities, such as considering the effects of other celestial bodies, atmospheric drag, and orbital adjustments. However, understanding the principles of gravitation is essential for studying and analyzing satellite motion and celestial mechanics.
