How come in free fall you feel weightless even though gravity is pulling down on you?

How come in free fall you feel weightless even though gravity is pulling down on you?

When in free fall, the only force acting upon your body is the force of gravity – a non-contact force. Since the force of gravity cannot be felt without any other opposing forces, you would have no sensation of it. You would feel weightless when in a state of free fall.

Why does a person in free fall experience weightlessness while a person falling at terminal velocity does not?

A person in free fall experiences weightlessness because there is no support force on him. A person falling at terminal velocity does not experience weightlessness because of the support force provided by the air, which equals mg .

Does terminal velocity make you weightless?

Terminal velocity is obtained for an object when the upward drag force (coming from the fluid the object is moving through) and the weight of the body balances. So the net force acting on the object is zero. This is not weightlessness.

What happens when feel weightless?

Feeling “Weightless” When You Go “Over the Hump” The phenomenon of “weightlessness” occurs when there is no force of support on your body. When your body is effectively in “free fall”, accelerating downward at the acceleration of gravity, then you are not being supported.

Why do astronauts feel weightless in orbit?

(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. Thus, the astronaut is falling. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.

Why is it incorrect to say that astronauts are weightless?

(A) An astronaut standing on Earth does not feel weightless because the ground creates a normal force that opposes the force of gravity. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.

What happens when a person reaches terminal velocity?

In very high falls, bodies can reach terminal velocity, the speed at which air resistance becomes so high it cancels out the acceleration due to gravity. Once at terminal velocity, you can fall as far as you like and you won’t gather any more speed.

Why is space weightless?

The astronauts, the ISS itself and other objects in Earth orbit aren’t floating, they are actually falling. So, as they accelerate towards the Earth, the Earth curves away beneath them and they never get any closer. Since the astronauts have the same acceleration as the space station, they feel weightless.

What happens to the weight of an object at Terminal Velocity?

at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero The weight of an object does not change as it falls, as long as it stays whole.

What is the terminal velocity of a human body?

The terminal velocity of an average 80 kg human body is about 66 meters per second (= 240 km/h = 216 ft/s = 148 mph). Terminal velocity can be achieved by an object provided it has enough distance to fall through so if you want to experience it, you need to jump from a high enough place (do not forget your parachute!).

What happens to the downward force of gravity at Terminal Velocity?

When terminal velocity is reached, the downward force of gravity is equal to the sum of the object’s buoyancy and the drag force. An object at terminal velocity has zero net acceleration.

What is the difference between free fall and terminal velocity?

Take a look at the definitions and equations of the terms, how they are related, and how fast a body falls in free fall or at terminal velocity under different conditions. Terminal velocity is defined as the highest velocity that can be achieved by an object that is falling through a fluid, such as air or water.
