Question

gravity is a fundamental interaction in the universe. the gravitational force between two celestial objects can be determined using newtons law of universal gravitation. determine whether each statement is true or false. the gravitational force between a 1 ( m_odot ) star and a 0.5 ( m_odot ) star separated by a distance of 100 light - years is stronger than the gravitational force between a 1 ( m_odot ) star and a 0.5 ( m_odot ) star separated by a distance of 10 light - years. gravity is a type of energy that can be found throughout the universe. if a planet has two moons that are each 300,000 kilometers away, the gravitational force will be stronger between the planet and the more massive moon than between the planet and the less massive moon. a planet exerts the same gravitational force on a star as the star exerts on the planet, just in the opposite direction. but since the planet is less massive than the star, it will be more significantly impacted by the stars gravitational pull.

Explanation:

1. Newton's law of universal gravitation states gravitational force is inversely proportional to the square of distance. Larger distance means weaker force.
2. Gravity is a fundamental force, not a form of energy. Gravitational potential energy is related but distinct from gravity itself.
3. Gravitational force is directly proportional to the product of masses. With equal distance, a more massive moon creates a stronger force with the planet.
4. Newton's third law dictates mutual gravitational forces between two objects are equal in magnitude and opposite in direction. Less massive objects accelerate more under the same force, so the planet is more impacted.

Answer:

1. False
2. False
3. True
4. True
