If a bee flies into a lift and the lift goes up while the bee is hovering in the air, will the bee move in proportion to the lift or will it hit the floor?

charlize SG

Hit the floor.

ThunderFbolt SG

i think it will hit the floor only if it is close to the floor in the first place. if it is hovering in the middle of the lift, while it will move closer to the floor in the initial moments of the upward movement, so will the air particles in the lift, creating a higher pressure at the bottom of the lift, and giving time for the bee to react (assuming it does react, i'm not a bee so i don't know) before the pressure rights itself and all the molecules move proportionally with the lift.

probably should get a flying insect in a lift to test it out.

skythewood SG

no need experiment. it will hit the floor.

Different frames of reference.

Bee is in an inertial frame of reference (consider it doesnt move- constant/at rest), while the lift is in a non-inertial frame of reference (accelerating upwards in this case). So ya, bee will hit the floor if the lift goes up.

haha cute question ^^. It will hit the floor. But it doesn't straight away hit it. It will slowly move downwards.

Its impossible to test, though i would think the change in pressure between the wings and the floor would prevent collison

change in prez? i dont see how. Besides, a simple analogy to this:

find a toilet paper spool,

cover both ends, and poke a hole through the ends.

pass a string through it and attach a small weight onto it.(weight to be left hanging inside the spool)

Leave one frame(eg, the weight) constant,

and move the other(spool) either up or down.

CONFIRM WILL HIT ONE.

so...... will u fly backwards if you jump in a moving MRT? :)

caleb_chiang SG

It will still be hovering as it is an enclosed environment.

Yes, you will fly backwards if you can hold yourself in the air long enough, and when the train is just starting to move off. But it has to move from 0 to something faster than you can hold yourself in the air long enough to prove that.

Haha! One of the best questions on Einstein's theory of relativity. The answer depends whether you'r in the lift, or outside it. Go read up =)

this is not Einstein's theory of relavity, this is Galileo's principle of relativity. Galileo explains inertia frames, Einstein's explains time frames.

yup. as i said before. inertia frames :)

You won't coz you'll already be moving at the same speed as the MRT, unless in the scenario that ditzy puts across

deepak.c SG

The bee will move with the lift and not hit the floor.

The air which the bee hovers in is also moving with the same velocity as the lift.

The bee will stung your balls.

The bee will stung your balls.

funny right? I also tink its funny.
