Question

Students analyze their data from a gravity experiment. They find that objects fall at a greater speed from a greater height than from a lower height. What can they conclude? (1 point)
• The longer an object falls, the greater its mass.
• The experiment must have a design flaw.
• Students must have mismeasured the objects' drop times.
• The longer an object falls, the more gravity increases its speed.

Answer 1

The longer an object falls, the more gravity increases its speed.

Explanation: Gravity produces a constant acceleration, so an object’s speed increases the longer it falls. Mass doesn’t change, and the result doesn’t necessarily mean there was a design flaw or mismeasurement.
