* Gravity's Pull: Earth's gravity exerts a constant downward force on objects near its surface. This force causes objects to accelerate downwards.
* Acceleration: Acceleration means a change in velocity over time. So, as an object falls, its velocity continuously increases.
* Air Resistance: In real-world scenarios, air resistance plays a role. As an object falls faster, air resistance increases, eventually opposing gravity. This leads to a point where the object reaches *terminal velocity*, a constant velocity where the forces of gravity and air resistance balance out.
In summary:
* Falling objects have a constant acceleration due to gravity.
* Their velocity increases as they fall.
* Air resistance can eventually cause the object to reach terminal velocity.
