Here are the answers to your questions:
Question 11: What would happen to the force between Earth and the sun if the mass of the sun tripled?
- Response: The force would be tripled.
(The gravitational force is given by Newton's law of gravitation, which states that the force \( F \) is proportional to the product of the masses of the objects: \( F = G \frac{m_1 m_2}{r^2} \). If the mass of the sun triples, the force of gravity between the Earth and the sun would also triple.)
Question 12: What happens to the acceleration of an object as the mass of an object increases?
- Response: Decreases.
(According to Newton's second law, \( F = ma \) (force equals mass times acceleration). If the mass increases while the force remains constant, the acceleration must decrease.)
Question 13: When would the force of gravity between two objects grow stronger?
- Response: When the objects get closer to each other.
(The gravitational force increases as the distance between two objects decreases, following the inverse square law in Newton's law of universal gravitation.)
Question 14: What force pulls planets into a curved path when they are orbiting the sun?
- Response: Gravity.
(Gravity is the force that causes planets to follow curved paths around the sun, as it pulls them toward the sun while they also have a forward motion.)
