In freefall, an object is in a state of weightlessness because the force of gravity is the only force acting upon it. Weightlessness occurs when the sum of all forces on an object is equal to zero, therefore the object has no acceleration. In other words, the object is not being pulled in any direction.
The Solar System is composed of the Sun, the eight planets and their moons, dwarf planets, asteroids, comets, and other small bodies. All of these objects are held together by the force of gravity, which is the force of attraction between any two objects with mass. The Sun is the most massive object in the …

Mass is the amount of matter an object contains, while weight is the force of gravity on an object. Mass is measured in kilograms (kg) and weight is measured in Newtons (N).
Uniform Acceleration: Uniform acceleration is a type of motion in which the velocity of an object changes by the same amount in a given amount of time. This type of motion is also known as constant acceleration. An example of uniform acceleration is a car accelerating at a constant rate from 0 to 6 miles …
The weight of a body is determined by its mass and the force of gravity acting on it. The force of gravity is determined by the mass of the body and the distance from the center of the Earth. As a result, the weight of a body is directly proportional to its distance from the …
Acceleration due to gravity is the rate at which an object accelerates when it falls freely near the Earth’s surface. The acceleration due to gravity is denoted by “g” and is equal to 9.8 m/s2.
1. Gravity: Gravity is a force of attraction between two objects with mass. It is the force that keeps the planets orbiting the sun and is responsible for the movement of objects on Earth and in the universe. Gravity is one of the four fundamental forces in nature. 2. Electromagnetism: Electromagnetism is the force of …

The force of gravity between two objects is equal to the product of their masses divided by the square of the distance between them, multiplied by the gravitational constant: F = G * m1 * m2 / r2 where F is the force of gravity G is the gravitational constant (6.67 x 10-11 Nm2/kg m1 …
Kepler’s laws of planetary motion are three scientific laws describing the motion of planets around the Sun. The laws are named after the German astronomer Johannes Kepler, who first published them in 1609. The first law states that all planets move in elliptical orbits with the Sun at one focus. The second law states that …
The Universal Law of Gravitation 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. This force is often referred to as gravity.
