Question

students drop objects from a height and measure the time it takes each to reach the ground. what is the variable in this experiment?
options:

• falling time
• object dropped
• drop height
• force at which the object falls

Explanation:

In this experiment, students drop objects from a fixed height (so drop height is constant) and measure the time each object takes to fall. The variable is what's being measured or what changes as different objects are dropped. The "falling time" is what's being measured for each object, while "object dropped" is the independent variable (the different objects), "drop height" is constant, and "force at which the object falls" isn't the focus here. So the variable in the experiment (the dependent variable being measured) is falling time.

Answer:

A. falling time
