The total number of Kepler's Laws of Planetary Motion
What is 3?
There are this many NASA identified planets in our solar system.
What is 8?
Gravity is a force that does this to all objects.
What is pull/pull together?
This is the formula used to calculate DENSITY of objects.
What is mass divided by volume?
What is D = m/v?
Objects that float in water are __________ dense than water.
What is less?
Kepler's first law explains that all orbits are shaped like this
What is an Ellipse/Elliptical?
This planet has the shortest orbital period of 88 days.
What is Mercury?
The strength of an objects gravity is directly proportional to its..
What is mass?
This is the formula to calculate how much force is needed to move an object.
What is mass times acceleration?
What is F = ma?
The planet with the longest orbit is this one, with an orbital period of 60,190 days!
What is Neptune?
This one of Kepler's laws can be used to calculate how long a planet's orbit will be
What is Kepler's Third Law?
These planets are often composed of rocks and metal materials
What are inner planets?
What is Mercury, Venus, Earth, and Mars?
The further away two objects are the ________ their gravitational forces are.
What is weaker?
What is a density of 5 g/cm3?
Most of the planets are named after these.
Kepler's second law explains that this happens to planets as they get closer to the sun
What is an increase in velocity/gravitational pull?
These planets are composed of gaseous materials and have thick atmospheres
What are outer planets?
What are Jupiter, Saturn, Uranus, and Neptune?

Based on the following image, these planets will have a stronger gravitational pull.
What are planets B?
What is 180 N?
This is largely responsible for what the planets are made out of.
What is temperature?

Pictured here is two points of a planet's orbit. Where is the velocity of the planet going to be the fastest?
Where is point A?
This is the planet with the lowest density (0.68 g/m3) in our Solar System.
What is Saturn?
If the mass of two objects were to double in size, then this would happen to the gravitational force.
What is quadruple?
This is the gravitational constant on planet Earth.
What is 9.8 m/s2?
This is largely responsible for how dense the planets are.
What is gravity/the sun's gravity?
