# astronomy

Newton’s Law of Universal Gravitation is an equation:

## Forcedue to Gravity=GMassof the larger objectMassof the smaller objectDistancebetween objects2

G is the gravitational constant. For today, just assume it is 1 and you can ignore it. You can do this because it is simply a number and doesn’t affect the relationship between the other values.

Let’s examine the Force (due to Gravity) between the Earth (the larger object) and the Moon (the smaller object.

- How would the Force (due to Gravity) between the Earth and the Moon change if the Moon were suddenly 2 times its current mass?
- Would the Force (due to Gravity) increase or decrease?
- By how many times?

- How much Force (due to Gravity) is there between the Earth and the Moon?
- How much Force (due to Gravity) does the
__Earth exert__on the__Moon__? Fill in the blanks on this equation**with words**in order to answer this question.

## Forcedue to Gravity=GMass_________________________Mass__________________Distance_______________________2

- How much Force due to Gravity does the

## Forcedue to Gravity=GMass_________________________Mass__________________Distance_______________________2

- How do these two compare?

The strength of the Force (due to Gravity) that the __Earth__ exerts on the __Moon__

versus

The strength of the Force (due to Gravity) that the __Moon__ exerts on the __Earth__

- Are they the same or different?
- Study the picture below.
. This is a spacecraft travelling away from the Earth.**It is not to scale at all**

- Assume the spacecraft travels in a straight line away from the Earth. Label the point where the Force (due to Gravity) from the Earth on the spacecraft is the strongest.
- Now label the point where the Force (due to Gravity) from the Earth on the spacecraft is the weakest.
- Draw a point halfway between the Earth and the spacecraft, label that point A. Label the spacecraft’s current position as point B. The distance from the Earth to point A is 1. Label the distance from the Earth to point B as 2.
- Fill out this equation for when the spacecraft is at point A. Use numbers for distance:

## Forcedue to Gravity=GMass_________________________Mass__________________Distance_______________________2

- Fill out this equation for when the spacecraft is at point B:

- Simplify the equations in parts 4a and 4b. You’ll end up making all variables that are the same equal to 1, and comparing just the difference. You should have Force=a fraction for both:
- How would the Force (due to Gravity) between the Earth and the Moon change if the Moon were suddenly 2 times farther away?
- Would the Force (due to Gravity) increase or decrease?
- By how many times?

- Study the picture below.
. This is a spacecraft travelling from the Earth to Mars.**It is not to scale at all**

- Draw a straight line path between the Earth and Mars.
- Remember that this spacecraft is halfway along its journey between the Earth and Mars. Where along that path would the Force (due to gravity)
__from Earth__be strongest__on the spacecraft__?

Label this point on the diagram.

- Where along that path would the Force (due to gravity)
__from Mars__be strongest__on the spacecraft__?

Label this point on the diagram.

- Now. Where along the path would the Force (due to gravity)
__on the spacecraft__be balanced (equal)__from Mars__and__from the Earth__?

Label this point on the diagram.

- When you finish that, write out the equations for the Force (due to gravity) on the spacecraft due to Mars and also due to Earth. Solve for distance. Remember that the distance to Earth is not the same as the distance to Mars.
