Question

this force has existed since the very beginning of the universe. gravity attracts all objects towards each other. it is an invisible force that pulls, and gravity works the same way everywhere in the universe. sir isaac newton discovered gravity about 300 years ago watching apples fall from a tree. anything that has mass, has gravity. isaac newtons law of universal gravitation states that every object in the universe exerts a force on every other object. the strength of the force of gravity depends 2 factors: mass and distance. mass and weight an object that is more massive will exert a greater gravitational force. weight is the force of gravity on an object. your weight on earth is how much force earths gravity is pulling on you. a persons weight changes depending on its location. if you could stand on the surface of the sun, you would weigh more than standing on earth. distance the force of gravity is also affected by the distance between two objects. the closer together, the stronger gravitational force. as distance increases between objects, the force of gravity weakens. inertia a force that continually moves a planet forward what would happen to the force of gravity if... gravity will... increase, decrease or stay the same the mass of the sun increased neptune moved farther away from the sun the sun released a huge solar flare the earths mass became smaller use the reading and the diagram above to answer the following questions. you will use one word more than once. moon strength neptune earth sun mass 1. all objects with __________ have gravity. 2. the ________ of the force of gravity depends on mass and distance. 3. ________ this object has the weakest force of gravity, due to its small mass. 4. ________ this planet experiences the strongest force of gravity from the sun. 5. ________ this object has the strongest force of gravity, due to its large mass. 6. ________ this planet experiences the weakest force of gravity from the sun. 7. gravity keeps the __________ moving around the earth.

Explanation:

Step1: Recall gravity - mass relationship

According to Newton's law of universal gravitation, the force of gravity is directly proportional to mass. So, if the mass of the Sun increases, the force of gravity increases.

Step2: Recall gravity - distance relationship

The force of gravity is inversely proportional to the square of the distance. When Neptune moves farther away from the Sun, the force of gravity decreases.

Step3: Analyze solar - flare effect

A solar flare is an ejection of plasma and magnetic field from the Sun's surface and does not directly change the mass of the Sun significantly in the context of gravitational force calculations. So the force of gravity stays the same.

Step4: Analyze Earth - mass change

Since the force of gravity is directly proportional to mass, if the Earth's mass becomes smaller, the force of gravity decreases.

Step5: Answer fill - in - the - blanks

1. All objects with mass have gravity.
2. The strength of the force of gravity depends on mass and distance.
3. Moon. This object has the weakest force of gravity, due to its small mass.
4. Earth. This planet experiences the strongest force of gravity from the Sun among the ones listed here (compared to Moon and Neptune in a simple sense as it is closer and has a reasonable mass).
5. Sun. This object has the strongest force of gravity, due to its large mass.
6. Neptune. This planet experiences the weakest force of gravity from the Sun among the planets listed as it is the farthest.
7. Gravity keeps the Moon moving around the Earth.
