If ______ is the only force acting on an object, the object is said to be in free fall.Multiple choice question.accelerationdecelerationgravityfriction

Break Down the Problem

1. Identify the forces that can act on an object.
2. Understand the condition under which an object is considered to be in free fall.

Relevant Concepts

1. Free Fall: An object is in free fall when the only force acting on it is gravity, leading to acceleration due to gravitational force.
2. Forces:
   • Acceleration: A change in velocity over time but not a force itself.
   • Deceleration: A decrease in speed; also not a force.
   • Gravity: The force that attracts a body toward the center of the Earth.
   • Friction: A force that opposes motion, not applicable in free fall.

Analysis and Detail

• In free fall, the only force acting on the object is gravity, meaning that regardless of other forces like air resistance, for the purpose of the definition, gravity is considered the primary force when discussing free fall conditions.

Verify and Summarize

• Considering all options, the only force that qualifies as the sole acting force on an object that leads to free fall is gravity.

Final Answer

The correct answer is gravity.
