* Freefall means only gravity acts: Freefall is defined as the motion of an object where the only force acting on it is gravity.
* Gravity causes acceleration: Gravity exerts a constant force on objects, pulling them towards the center of the Earth. This force causes an acceleration, meaning a change in the object's velocity.
* Constant acceleration: The acceleration due to gravity is constant near the Earth's surface, approximately 9.8 m/s². This means the object's velocity will continuously increase as it falls.
Important Note: While an object in freefall will have a constant acceleration, its velocity can be zero at a specific point in time. For example, if you throw an object straight up, it will momentarily have zero velocity at its highest point before it starts falling back down. However, it will still be accelerating due to gravity during this entire motion.
