Be cool to each other. We'll welcome most occult themes, it's okay if you stray from witchcraft a bit.

No advertising. No trolling. No hate. Violaters will be removed unceremoniously.

We love art credits when possible.

Torque is a measurement of rotational force. Brooms would technically have thrust. If I remember my high school physics, a Broom would need at least 980 Newtons of thrust to liftoff your average sized witch.

What’s an average sized witch?

[–] Player2@lemm.ee 14 points 1 month ago (1 children)

Probably one with under about 980 Newtons weight

i mean you have to account for air resistence and you need enough lift to actually fly. and we are not talking about the best aerodynamics here.

About the weight of a duck.

Assuming that's it's just the normal force of Earth's gravity at work on the witch, it's just a case of working Newton's second backwards with the gravitational "constant" acceleration ≈ 9.8 m/s²:

F = ma

980 N = m × 9.8 m/s²

980 / 9.8 = (m × 9.8) / 9.8, units omitted for text clarity

100 kg = m

In other words, op is assuming that an average size witch masses approximately 100kg (or about 220 lbs in fingers, knees, and toes units).

That's not enough for flight, only enough to nullify gravity. It makes sense OP would leave some trust for acceleration

They'll flap their arms for propulsion

Using Hocus Pocus as a data sample, Bette Midler is the average sized witch.

So no torque, then? Unless the witches are rotating so fast we can't perceive it with the human eye, like a car's wheels travelling alongside you at a particular speed.

Brooms can put out a variety of uggaduggas depending on the model.

Comets suck, Nimbus are good, Firebolts will kill you of you're a moron.

Children should be eaten and not heard.

Yea, that sounds about right... (¬_¬)
