Level 1
the bending of spacetime caused by mass.
What is gravity?
This equation represents a stable orbit.
G=V
Equation for eccentricity
e=f/d
This unit measures the distance from the Earth to the Sun.
What is AU
Stars create strong gravity because they have a lot of this
What is mass
When an object crashes into a planet, gravity and velocity are no longer balanced, meaning this happened to the orbit.
Orbit became unstable or gravity or velocity increase/decreased
Between eccentricities 0.8 and 0.4, this one is more elliptical.
what is 0.8
In the formula P² = A³, P represents this.
Orbital period how long it takes
This happens to an object’s velocity when it moves closer to the Sun’s gravitational pull
What is increasing?
This Kepler law explains why planets speed up when closer to the Sun.
What is kepler's second law
Between eccentricities 0.8 and 0.4, this one is faster and uses which of Kepler's laws
0.4 closer to the sun and doesn't slow down as much kepler's 2 and 3rd law. Velocity speeds up when closer due to gravity increasing and slows when further.
An asteroid with an average distance of 71 AU has an orbital period of about this many years.
What is 598 years?
This happens when the gravitational force becomes weaker than an object's velocity
What is an object flying out of orbit
This law tells us that planets farther from the sun take longer to orbit.
What is kepler's 3rd law
Using the formula E = F/D, an orbit with A = 600 and B = 1000 has this eccentricity.
0.6
If a planet has an orbital period of 15 years, its average distance from the Sun is about this.
What is 6.1 AU?
This measurement depends on gravity—more mass, more gravity, more of this.
What is weight?
According to Kepler’s Second Law, planets do this when they are farther from the Sun.
Move slower
Between eccentricities 0.8 and 0.4, this one is more elliptical. and slower
