Gravitation

Answer

Gravitational force is the force of attraction between any two objects in the universe. It acts along the line joining the centers of the two objects. For example, the Earth attracts an apple towards

Answer

Every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them. The fo

Answer

F = GMm/d² Where: F = gravitational force between two objects G = universal gravitational constant (6.67 × 10⁻¹¹ N m² kg⁻²) M = mass of first object m = mass of second object d = distance between cent

Answer

Value: G = 6.67 × 10⁻¹¹ N m² kg⁻² SI Unit: N m² kg⁻² (Newton meter squared per kilogram squared) G was experimentally determined by Henry Cavendish using a sensitive balance.

Answer

Free fall is the motion of an object under the influence of gravitational force alone. During free fall, objects fall towards Earth with acceleration due to gravity (g). Example: A stone thrown upward

Answer

Acceleration due to gravity (g) is the acceleration experienced by any object during free fall due to Earth's gravitational pull. Its value on Earth is approximately 9.8 m/s². The direction is always

Answer

From F = GMm/R² and F = mg Therefore: mg = GMm/R² Canceling m from both sides: g = GM/R² Where: G = universal gravitational constant M = mass of Earth R = radius of Earth

Answer

From g = GM/R², we see that acceleration due to gravity is independent of the mass of the falling object. It depends only on Earth's mass (M) and radius (R). Therefore, whether light or heavy, all obj
