Questions and Answers

What is the formula for gravitational force between two objects?

F = G * (m1 + m2) / r
F = G * (m1 * m2) / r
F = G * (m1 + m2) / r^2
F = G * (m1 * m2) / r^2 (correct)

What is the universal law of gravitation?

It states that every object in the universe is attracted to the Earth with a force that is directly proportional to the object's mass.
It states that the force of gravity between two objects is directly proportional to the distance between their centers.
It states that the force of gravity is inversely proportional to the product of the masses of the objects.
It states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. (correct)

What did Newton's law of universal gravitation help explain?

The motion of the planets around the Sun. (correct)
The transmission of sound waves through different mediums.
The process of photosynthesis in plants.
The behavior of light in a vacuum.

What is the difference between mass and weight in the context of gravitation?

Mass is the amount of matter in an object, while weight is the force of gravity acting on that object's mass. Signup and view all the answers

Explain the concept of gravitational potential energy and its relevance to gravitation.

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It is relevant to gravitation as it explains how energy is stored in an object due to its position relative to other objects with mass. Signup and view all the answers

Discuss the impact of gravitation on the motion of celestial bodies in the universe.

Gravitation influences the motion of celestial bodies by causing them to orbit around each other or follow certain trajectories due to the gravitational force exerted by massive objects. Signup and view all the answers
