Question

An object is said to be in a state of free fall when:

• A. It accelerates under the force of gravity.
• B. When the only force acting on it is the weight of the object.
• C. Initial velocity can be a zero or a non-zero value.
• D. All of these.

Answer 1

The correct option is B

When the only force acting on it is the weight of the object.

Freefall is the motion of a body where its weight (gravitational force) is the only force acting upon it.

On Earth, a body in free fall experiences an acceleration equal to $g=9.8m/s^2$. Thus, falling through an atmosphere without a deployed parachute or lifting device is also often referred to as free fall.
