Gravitational Force and Universal Gravitation Quiz

Gravitational Force and Distance

• Doubling the distance between two objects decreases the gravitational force between them by a factor of four, according to the inverse square law.

Formula for Gravitational Force

• The formula to calculate gravitational force (F) between two objects is given by:
  [ F = G \frac{m_1 m_2}{r^2} ]
  Where ( G ) is the gravitational constant, ( m_1 ) and ( m_2 ) are the masses of the objects, and ( r ) is the distance between their centers.

Law of Universal Gravitation

• Sir Isaac Newton proposed the law of universal gravitation, which describes the gravitational attraction between masses.

Acceleration Due to Gravity

• The acceleration due to gravity at the surface of the Earth is approximately ( 9.81 , m/s^2 ).

Direction of Gravitational Force in Free Fall

• The gravitational force acting on an object in free fall directs downward toward the center of the Earth.

Relationship Between Gravitational Force and Mass

• The gravitational force is directly proportional to the mass of the objects involved; as the mass of either object increases, the gravitational force between them increases.
