When an object free falls, its accerleration is constant, but does its speed change? If so is it practicing uniform or non uniform motion?
Why do you mistakenly conclude that a free falling object's coordinate acceleration is always constant?isyang94 said:When an object free falls, its accerleration is constant, but does its speed change? If so is it practicing uniform or non uniform motion?
The constant speed of free falling objects is the rate at which an object falls towards the ground due to the force of gravity, without any other forces acting on it. This speed is approximately 9.8 meters per second squared, and is also known as the acceleration of gravity.
All free falling objects have the same constant speed because they are all affected by the same acceleration of gravity, regardless of their mass or size. This means that regardless of their weight, all objects will fall towards the ground at the same rate.
No, the constant speed of free falling objects does not change as long as there are no other forces acting on the object. This means that in a vacuum, where there is no air resistance, the object will continue to fall at a constant speed until it reaches the ground.
Air resistance can affect the constant speed of free falling objects by slowing down the object's descent. As an object falls through the air, it experiences a force in the opposite direction of its motion, which can reduce its speed. This is why objects with a larger surface area, such as a feather, fall slower than objects with a smaller surface area, such as a rock.
Yes, the constant speed of free falling objects can be greater than 9.8 meters per second squared if the object is falling in a location with a stronger gravitational pull, such as on a different planet. The acceleration of gravity can vary depending on the mass and distance between objects. However, on Earth, the acceleration of gravity is always approximately 9.8 meters per second squared.
