Which statement about an object in free fall is false?

An object in free fall is subject to the force of gravity acting on it, which causes it to accelerate downward at a constant rate, specifically about 9.8 m/s² on Earth. This acceleration means that the speed of the object is not constant; instead, it increases as it falls due to that gravitational pull.

When considering the different statements, the one that is false is the assertion that the object travels at a constant speed before hitting the ground. In free fall, assuming there is no significant air resistance, the speed cannot be constant because the object is continuously accelerating. Each passing second, the object's speed increases as a direct result of gravitational acceleration.

The other statements accurately reflect the behavior of an object in free fall. It does indeed accelerate downwards due to gravity, it increases speed as it falls, and air drag does act against the motion, but only significantly for objects that are falling through an atmosphere and at lower velocities before reaching terminal velocity. Thus, statement B misrepresents the nature of free fall regarding speed.
