Equations
This is newton’s Law of Universal Gravitation
F=G(m1m2)/r^2
The law that states that the orbit of the planets is elliptical in shape, with the center of the sun being at one focus.
What is Kepler's First Law
This is how gravitational force changes in relation to distance.
What is Kepler’s Third Law in equation form?
This is the maximum gravitational potential energy.
0
This is the path which objects in orbit take.(Might be inaccurate?
What is an ellipse?
This equation gives gravitational field strength.
g=GM/r^2
This law stating that a line joining a planet and the Sun sweeps out equal areas in equal times.
What is Kepler's Second Law?
How is orbital speed related to radius in circular orbits?
V is proportional to 1/r^1/2
This is what happens to gravitational potential energy when the mass of an object increases.
The gravitational potential energy increases
What are the 2 points at which an object is closest and farthest from the body it is orbiting called.
Aphelion and Perihelion
This equation is the velocity of an object in a stable circular orbit.
v=(GM/r)^1/2
What is Kepler’s Third Law in equation form?
T^2=ka^3
As mass increases, what happens to gravitational potential energy?
It becomes more negative
What is radial distance between the 2 masses.
This is a type or orbit in which the object matches the rotation of the object it follows
What is Geosynchronous orbit
This equation is used to find escape velocity.
v=(2GM/r)^1/2
Kepler’s laws are a consequence of these physical laws.
What are Newton's Laws of Motion and Universal Gravitation?
Relationship between period and radius for circular orbit?
T∝r^3/2
This is what it means if an objects gravitational potential energy is 0
What is, the object is at infinite distance
This is what the time it takes to make a full orbit is known as.
What is the orbital period
This equation can be used to find the total mechanical energy of an orbiting satellite.
E=-(GMm)/2r

What is at perihelion?
What is an increase in gravitational potential energy and decrease in kinetic energy
