- Changing Distance: For each scenario below calculate how an initial light intensity of 144 lumens changes.
- The projector is moved 2x farther away from the whiteboard.

- The projector is moved 4x farther away from the whiteboard.

- The photographer moves her light 3x times closer to the subject (1/3 the beginning distance).

- The projector is moved 2x farther away from the whiteboard.
- Changing Distance: For each scenario below calculate how an initial gravitational attraction of 36N changes.
- Two objects in space move apart to 2x the distance they were.

- Two objects in space move apart to 3x the distance they were.

- Two objects in space move 3x closer together (1/3 the beginning distance).

- Two objects in space move apart to 2x the distance they were.
- Changing Mass: For each scenario below calculate how an initial gravitational attraction of 36N changes
- Two objects in space are kept at the same distance but their total mass is doubled.

- Two objects in space are kept at the same distance but their total mass is tripled.

- Two objects in space are kept at the same distance but their total mass is 1/3 of what it was.

- Two objects in space are kept at the same distance but their total mass is doubled.
- Changing Distance and Mass: For each scenario below calculate how an initial gravitational attraction of 36N changes.
- Two objects in space move 2x closer and their total mass is doubled.

- Two objects in space move 2x closer and their total mass is 1/2 what it was.

- Two objects in space move 2x closer and their total mass is doubled.
