.
speed
mass
time
kinetic energy

Explanation:

To solve this, we analyze the context (likely a physics lab on kinetic energy, \( KE = \frac{1}{2}mv^2 \)):

Part I Independent Variable:

In typical kinetic energy experiments, if testing how speed/mass affects KE, the intentionally manipulated (independent) variable is often speed or mass first. If Part I manipulates speed (to see KE change), the independent variable is speed.

Part II Independent Variable:

If Part II shifts to manipulating mass (to see KE change with mass), the independent variable becomes mass.

Dependent Variable:

The dependent variable (measured response) is kinetic energy (since \( KE \) depends on speed/mass, which are manipulated).

Answer:

s (assuming a common kinetic energy lab flow):

• Part I independent variable: speed
• Part II independent variable: mass
• Dependent variable: kinetic energy

(Note: The exact answer depends on the lab’s design, but this aligns with \( KE = \frac{1}{2}mv^2 \), where \( KE \) depends on \( m \) (mass) and \( v \) (speed), with one manipulated at a time.)
