Kepler’s Laws

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun

The farther away a planet is from the sun, the _______ it takes it to orbit the sun once. 

• longer
• shorter

What are the two factors that influence gravity the most?

• Mass and weight
• Weight and gravity
• Mass and distance
• Weight and distance

Where is the planet moving faster

• Position A to B
• Position B to C
• Position H to I
• Position I to J

What is true about the area between points A, B and the Sun, and the area between points H, I and the Sun?

• The area between A, B and the Sun is the largest.
• The area between H, I and the Sun is the largest
• Both areas are equal in size
• There is not enough information to determine the areas

Double the product of the masses of two objects

• 4 times stronger gravity force
• 4 times weaker gravity force
• 2 times weaker gravity force
• 2 times stronger gravity force

Double the distance between two objects

• 4 times greater gravity attraction
• 4 times weaker gravity attraction
• 2 times weaker gravity
• 2 times greater gravity

Which planet will take the most amount of time to revolve around the Sun?

• Mercury

• Venus

• Earth

• Mars

Which statement best describes Kepler’s 2^nd Law of Planetary Motion?​

• Planets revolve around the sun over equal areas in equal time intervals.

• Planetary orbits are in the shape of an ellipse.

• A planet’s orbital period is proportionate to its distance from the sun.
