Today’s lesson uses the Newton’s Law of Gravity Calculator.
Relationship between mass and gravitational force.
1. What is the gravitational force on an apple at the surface of the earth?
2. If you increase the mass of the apple by x2, what is the gravitational force?
3. If you increase the mass of the apple again by x2, what is the gravitational force?
4. Describe the relationship between the mass of the object and the gravitational force on it.
Relationship between radius and gravitational force.
1. What is the gravitational force between a 1 kg mass and the earth, at the radius of the earth?
2. If you increase the radius by x2, what is the gravitational force?
3. Reset the radius so it is back to 6.37 x10^6 meters. Increase the radius x3. What’s the gravitational force?
4. Explain the relationship between radius and gravitational force.
Different masses
1. What is the force of gravity between two people who are 1m away from each other? Is this force strong or weak?
2. What’s the force of gravity between a person and the earth on the surface of the earth?
3. What is the force of gravity between the earth and the sun at the distance to the sun?
4. What is the force of gravity between the earth and moon at the distance to the moon?
5. What force is stronger, the force between the earth and sun or the earth and moon?
6. Answer the question here and list the items in order of increasing strength. Write your explanation for why they are in that order.
7. Answer the question here, draw the planet and spacecraft, and list the order of increasing strength. Include an explanation for why they are in that order.
8. Answer the question here, draw the masses in their correct order, and explain how you know they should be in that order.
