This is the shape of planetary orbits.
What is an ellipse?
100
These are the variables that affect how much gravitational force exists between two objects?
What is mass and distance?
100
This is the slope of a position-time graph?
What is velocity?
100
This is the mass of an object on Earth's surface that weighs 748 Newtons.
What is approximately 74.8 kg (76.3 kg)?
100
This is the direction of the force vector for an orbiting object.
What is towards the large mass within the orbit (Sun, planet, etc)?
200
This is where the sun is located in an orbit.
What is at a focus?
200
This is how much the gravitational force will change if the mass of BOTH objects is quadrupled.
What is multiplied (increases) by 16?
200
This velocity vs time graph shows a change in direction.
What is SHOW ME THAT GRAPH?!?!?!
200
This is the gravitational force between two 8 kg pizza slices separated by 6 meters.
What is 1.2x10^-10 N (1.78xG)?
200
This is where acceleration is greatest within an elliptical orbit.
What is closer to the large mass within the orbit (Sun, planet, etc.)?
300
This is the speed of an object traveling in an elliptical orbit of 6.9x10^8 meters and an orbital period of 3,400 seconds.
What is 202,941.18 meters per second?
300
This is how much the gravitational force changes if the distance is increased by a factor of 5.
What is divided (decreases) by 25?
300
This graph shows the relationship between force of gravity and distance.
What is SHOW ME THAT GRAPH?!?!?!?!
300
This is the gravitational force between two objects, one with a mass of 1.97x10^23 kg and one with a mass of 3.4x10^5 kg and a distance of 3,723 meters between them.
What is 3.23x10^11 N?
300
This is the gravitational field around the Earth.
What is SHOW ME THAT DIAGRAM!?!?!
400
This is Kepler's Second Law of Planetary Motion.
What is a line drawn from a planet to the sun sweeps out equal areas in equal times?
400
This is the weight of a 150 kg object on the surface of the Earth?
What is approximately 1,500 (1470) Newtons?
400
This position-time graph shows an object in free fall.
What is SHOW ME THAT GRAPH!?!?!?!
400
What is the final velocity of two carts after collision. One cart is 20 kg and was at rest. The second cart was 10 kg and moving with a velocity of 5 m/s. The two carts stick together after the collision.
What is 1.67 m/s?
400
This is what "weightlessness" means.
What is an object accelerating at the same rate as its frame of reference (container/vessel/the thing its in)?
500
This is the speed of an object traveling with an orbital radius of 4.5x10^4 meters and an orbital period of 6,784 seconds.
What is 41.68 meters per second?
500
This is how much farther an object with nine times as much mass would have to be in order to have the same gravitational force on you.
What is three times as far?
500
This position-time graph shows a scholar moving in a negative direction toward the reference point, crossing the reference point, changing direction, moving at a greater speed to the reference point and then at rest.
What is SHOW ME THAT GRAPH?!?!?!?!
500
This is the mass of the Earth if you weigh 882 N and are 6.37x10^6 meters from the center of the Earth. Your mass is 90 kg.

500
This is what would happen if you fell into a black hole.
What is spaghettification?
