Newton's Laws
An object in motion, stays in motion unless acted on by an external force.
What is Newton's First Law
What is an orbit?
a geometric object that has a radius that is equidistant from the center for 360 degrees.
What is a circle?
when you burn this way you cancel out the force in the forward direction making you come to a complete stop
What happens when you burn backward?
What is Newton's Third Law?
the two points that determine the shape of an orbit, one of which is always occupied by the celestial body.
What are foci?
the line determined by calculating the distance between two points, or by taking the height and dividing by the length
What is the slope or hypothenuse?
you burn this way if you need to move in the +y direction
Why burn in -y?
The velocity of an object divided by time.
What is acceleration?
The highest point in an orbit
What is the apoapsis?
opposite/tan(angle)
What is the adjacent side?
How do you stop moving in +x and -y?
The change of motion (linear momentum) is proportional to the force impressed and is made in the direction of the straight line in which that force is impressed.
What is Newton's Second Law?
Why do we burn backward in orbit?
You get this when you divide the side opposite of the angle of interest by the hypothenuse
What is cosine?
you need to cancel out spins in each individual spin direction in order to stop this
How do you stop spin?
On any celestal body, the force will be the same on both objects as long as this is the same.
What happens when you drop two objects of the same mass?
The longest axis of an ellipse
What is the major axis?
SOH
You need to use a ______ orbit in order to catch up to an object that is moving faster then you
Why use a smaller orbit?
