The weight of a body is the measure of the gravitational force exerted by the Earth on it. It is defined as the force with which a body is attracted towards the center of the Earth. If g is the acceleration due to gravity at a particular location, then a body with mass m experiences a gravitational force mg towards the Earth’s center. Therefore, the weight of a body is given by W = mg.
In vector form, this is expressed as W = mg. Weight is a vector quantity and is measured in units of force, such as newtons or kilogram-force (kgf). Since the value of g varies from place to place, the weight of a body also changes depending on its location.
Gravitation: Gravitation is the force of attraction between any two bodies in the universe. Every object attracts every other object with this force, known as the force of gravitation. Examples include the attraction between the Sun and the Earth or between a table and a chair in a room. GravitationRead more

Examples include the attraction between the Sun and the Earth or between a table and a chair in a room. Gravitation is the weakest of the four fundamental forces in nature but plays a crucial role in the formation of stars and in shaping the structure and evolution of the universe.
Gravity: Gravity is a specific case of gravitation where one of the attracting bodies is the Earth. It refers to the force of attraction between the Earth and any object on or near its surface. For instance, when a body is thrown upward, it falls back to the Earth due to its gravitational pull.
Free fall refers to the motion of a body under the influence of gravity alone. If we ignore air resistance or friction, the fall of a body in air can be considered free fall. However, in reality, a body only falls freely in a vacuum. For a small, heavy body in air, the effect of air resistance is miRead more
Free fall refers to the motion of a body under the influence of gravity alone. If we ignore air resistance or friction, the fall of a body in air can be considered free fall. However, in reality, a body only falls freely in a vacuum. For a small, heavy body in air, the effect of air resistance is minimal, so its motion can be approximated as free fall.
When a body falls freely towards the Earth's surface, its velocity continuously increases. The acceleration responsible for this motion is called acceleration due to gravity. It is denoted by g and is a vector quantity directed towards the center of the Earth. The value of g is constant at a given lRead more
When a body falls freely towards the Earth’s surface, its velocity continuously increases. The acceleration responsible for this motion is called acceleration due to gravity. It is denoted by g and is a vector quantity directed towards the center of the Earth. The value of g is constant at a given location, but it varies across different places on Earth’s surface. Factors such as altitude, depth, Earth’s rotation, and its shape affect the variation of g. Acceleration due to gravity does not depend on the mass, size, or shape of the body. Using lasers, distances can be measured up to 10⁻⁹ meters, and time can be measured to an accuracy of 10⁻⁹ seconds with electronic devices. By observing the free fall of a body in a vacuum, g can be determined with an accuracy of 1 part in 10⁸. Near Earth’s surface, the value of g is approximately 9.8 m/s² or 32 ft/s².

The weight of a body is the measure of the gravitational force exerted by the Earth on it. It is defined as the force with which a body is attracted towards the center of the Earth. If g is the acceleration due to gravity at a particular location, then a body with mass m experiences a gravitational force mg towards the Earth’s center. Therefore, the weight of a body is given by W = mg.
In vector form, this is expressed as → W = m → g. Weight is a vector quantity and is measured in units of force, such as newtons or kilogram-force (kgf). Since the value of g varies from place to place, the weight of a body also changes depending on its location.
