Universal Law of Gravitation

The formula for the magnitude of the gravitational force between the earth and an object on the surface is given as $F = \frac{G \cdot M \cdot m},{R^2}$, where F is the force of attraction, G is the gravitational constant, M is the mass of the earth, m is the mass of the object, and R is the distance between the earth's center and the object (radius of the earth).

The universal law of gravitation states that every object in the universe attracts every other object with a force called the gravitational force. The force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Free fall refers to the movement of an object under the influence of Earth's gravity when it is dropped from a certain height, causing it to fall freely towards the surface of the Earth.

<p>Acceleration due to gravity refers to the rate at which the velocity of an object changes as it falls freely towards the Earth's surface under the influence of gravity.</p> Signup and view all the answers
