gravity
An object accelerates as it falls towards the ground due to the force of gravity acting on it. The object gains speed because gravity causes a constant acceleration towards the center of the Earth, increasing its velocity as it gets closer to the ground.
Applying heat to an object typically raises its temperature by transferring thermal energy to the object's molecules. This causes the molecules to move faster, increasing their kinetic energy and leading to a rise in temperature.
An object is hot or cold based on its temperature, which is a measure of the average kinetic energy of its particles. When particles move faster, they generate more heat, making the object feel hot. Conversely, when particles move slower, less heat is produced, causing the object to feel cold.
When the particles of an object move faster inside the object, their kinetic energy increases. The kinetic energy of a particle is directly related to its speed, so as particles move faster, their kinetic energy also increases.

It's all about the air resistance that the object receives as it falls in an atmosphere. The air has to move around the object as it falls, if it's allowed to move smoothly aroundyam object by the objects shape then the force of the air resistance is lower. This allows the object to fall faster.

why are some objects faster than other
When a force makes an object move, work is done.
An object is hot or cold based on its temperature, which is a measure of the average kinetic energy of its particles. When particles move faster, they generate more heat, making the object feel hot. Conversely, when particles move slower, less heat is produced, causing the object to feel cold.
Objects may move at different speeds because of how much mass they contain. Some objects also may have more propulsion than others which makes them able to travel faster.
what
And what makes you think an object would fall, or should fall, precisely at such a speed? How do you get that number? - Anyway, that's not the way our Universe works. Without air resistance, an object that falls downward falls faster and faster - its speed increasing by 9.8 meter/second every second. With air resistance, a falling object will eventually reach a speed at which friction (air resistance) balances the downward force of gravity. This speed is different for different objects.
heat which makes it move faster.
When the particles of an object move faster inside the object, their kinetic energy increases. The kinetic energy of a particle is directly related to its speed, so as particles move faster, their kinetic energy also increases.
