Uniform Circular Motion
This is time it takes for an object to go around a circle one time.
What is the period?
This is the feature of the circular path the object travels along.
What is the circumference?
This is the man responsible for coming up with the idea of universal gravitation.
Who is Isaac Newton?
Since satellites are only influenced by gravity, they are in this state.
What is free fall?
This is the direction of the velocity at any point along a circular path.
What is tangent?
What is 0.5 seconds?
The force of gravity is directly proportional to this value.
What is the mass of either object?
Satellites fall toward the earth at the same rate that this occurs.
What is the earth curving?
This is the direction of the acceleration of an object moving in a circle?
What is inward/toward the center of the circle?
For an object being twirled in a vertical circle on a string, these are the forces that act as the centripetal force when the object is at the top of the circle.
What are tension and gravity?
The force of gravity is inversely related to the square of this value.
What is the distance between the two objects?
This is the shape of the orbit in which the satellite travels at a constant speed at a constant distance from the massive body.
What is circular?
This is the definition of uniform circular motion.
What is when an object moves in a circle at a constant speed?
This is the net force of a 5kg object moving at 7m/s in a circle that has a radius of 10m.
What is 24.5N?
This is the value of constant G.
What is 6.67x10-11?
Work is done by gravity to cause an exchange of KE and PE in this kind of orbit.
What is elliptical orbit?
This is the force or combination of forces that causes an object to move in a circle.
What is centripetal force?
For a roller coaster at the bottom of a loop, this is the equation that relates net force, normal force, and force of gravity.
What is Fnet=Fnorm-Fgrav?
This is what happens to the force of gravity when the masses of each object double and the distance between the object doubles.
What is nothing/stays the same?
When a satellite is furthest from the massive body it orbits, this is highest and this is lowest.
What are PE (highest) and KE (lowest)?
