Choose the following FBD where the forces are balanced.
Calculate the Fnet of the FBD and describe the object's motion.
(Note: F air is the same as drag)
Fnet= 200N. It is speeding up as it falls down.
Fnet= 200N. It is traveling down at a constant speed.
Fnet= 1400N. It is speeding up as it falls down.
Fnet= 800N. It is traveling down and slowing down.
Fnet= 200N. It is traveling up and slowing down.
What claims can you make about this FBD? Check ALL that apply.
The forces are unbalanced.
The Fnet= 0 N.
The forces are balanced.
The object is speeding up.
The object is stopped or going at a constant speed.
Identify the independent variable in the following situation:
A scientist is studying how different amounts of light affect the growth of snake plants.
The growth of the snake plants
The type of soil used for planting
The amount of light for each plant
The amount of water given to each plant
Identify the dependent variable in the following situation:
A scientist is studying how different amounts of light affect the growth of snake plants.
The amount of light given to each plant
The growth of the snake plant
The amount of water given to each plant
The container that is used for planting
What is a controlled variable?
Something that causes a change in the other variables of an investigation.
Something that is changed by the other variables in the investigation.
A variable that is constant or unchanged throughout the investigation.
A variable that is the "cause" of the cause and effect relationship in the investigation.

What is the true statement regarding this FBD?
The forces are unbalanced.
The forces are balanced.
The forces are neither unbalanced nor balanced.
The object is accelerating to the left.
What is the true statement regarding this FBD?
The forces are balanced.
The forces are unbalanced.
The forces are neither balanced nor unbalanced.
The object is stopped.
Calculate the Fnet of the Free Body Diagram and describe the object's motion.
Fnet= 35N left, the object is speeding up as it travels left.
Fnet= 0N, the object is traveling at a constant speed.
Fnet= 40N down, the object is speeding up as it falls.
Fnet= 35N left, the object is slowing down as it travels right.
