That's correct. There's no air resistance in that equation.Jynku said:
It's not the acceleration that is constant, it's the gravitational force. (And that's only a reasonable approximation when you are close to Earth.)Jynku said:
It is assumed that there is vacuum around the falling object.Jynku said:
I don’t think there is any serious decrease in gravitational acceleration. We can take it as constant .PeroK said:
Do you know anything about air resistance?
The acceleration is most certainly reduced by air resistance, which is surely the point of the question. Look up "terminal velocity".rudransh verma said:
Free fall acceleration is the acceleration of an object due to the force of gravity. It is the rate at which an object falls towards the ground when no other forces are acting on it.
The value of free fall acceleration on Earth is approximately 9.8 meters per second squared. This value is constant and does not depend on the mass or size of the object falling.
Free fall acceleration is not affected by the mass of an object. This means that all objects, regardless of their mass, will accelerate towards the ground at the same rate when in free fall.
No, free fall acceleration is a constant value on Earth and does not change. However, it may vary on other planets or celestial bodies due to differences in their gravitational pull.
Free fall acceleration can be calculated using the formula a = g = F/m, where a is the acceleration, g is the gravitational constant (9.8 m/s^2 on Earth), F is the force of gravity, and m is the mass of the object.
