Which name is given to the type of friction that objects falling through air experience?
The type of friction that objects falling through air experience is called air resistance or drag. This friction force opposes the motion of the falling object, ultimately affecting its speed and trajectory.
Why do falling objects have a maximum speed?
Falling objects have a maximum speed due to air resistance. As an object falls, air resistance acts against gravity, eventually balancing out the force of gravity and limiting the object's speed. This is known as terminal velocity.
If objects falling through air experience a type of friction called?
If objects falling through air experience a type of friction, it is called air resistance. Air resistance is the force that opposes the motion of an object as it moves through the air. This force depends on factors such as the speed and shape of the object.
What is the significance of the cosmic speed limit in the context of the universe's expansion and the behavior of celestial objects?
The cosmic speed limit, also known as the speed of light, plays a crucial role in understanding the universe's expansion and the behavior of celestial objects. This speed limit determines how fast information and objects can travel through space. It influences the way light and other forms of energy propagate, affecting how we observe and interpret the universe. The cosmic speed limit also sets boundaries on the interactions between celestial objects, shaping the dynamics of galaxies, stars, and other cosmic structures.
Why do falling objects move faster than objects going upward?
Falling objects are accelerated by gravity, while objects moving upward are being decelerated by gravity. Gravity pulls objects downward, increasing their speed, while it opposes the motion of objects moving upward, decreasing their speed.

What is the highest speed possible for an object to travel?
The universal speed limit for material objects is c : the speed of light in a vacuum.

Why do falling objects speed up as they fall?
Falling objects speed up due to the acceleration of gravity. As an object falls, the force of gravity causes it to accelerate towards the Earth at a rate of 9.8 m/s^2. This acceleration increases the object's speed over time.
What do falling objects accelerate at a rate of?
Falling objects accelerate due to gravity at a rate of approximately 9.8 m/s^2 near the surface of the Earth. This acceleration is constant and causes objects to increase in speed as they fall.
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
How is it possible that the expansion of the universe is faster than the speed of light?
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
The speed when falling objects no longer accelerates due to air resistance is?
known as terminal velocity, which is reached when the force of gravity pulling the object downwards is balanced by the upward force of air resistance. At terminal velocity, the object falls at a constant speed with no further acceleration.
When falling objects no longer accelerate?
When falling objects no longer accelerate, they have reached terminal velocity. Terminal velocity is the constant speed achieved by an object when the force of air resistance matches the force of gravity acting upon it. At this point, the object stops accelerating and continues to fall at a constant speed.
