How does a potential divider work?

I've always thought that physics is best explained through analogies, and so instead of two resistors we'll imagine two people (our resistors) in Yo Sushi (where plates of sushi represent our voltage). Sa...

Do heavier objects fall on the ground quicker?

No. Physics can be and often is counterintuitive. Mass of an object doesn't affect the time of a fall. Different times are caused by air resistence and therefore are related to the shape. If we dropped a ...

Ann and Bob play on a uniform seesaw. The seesaw is 4m long and Ann and Bob weigh 600N and 800N respectively. If both Ann and Bob start at one end of the seesaw and Bob starts to walk up the seesaw at 2m/s, after how long will the seesaw turn?

(expect a diagram of a uniform seesaw with a pivot in the middle, infered from the question)

For the seesaw to turn, Bob must create a greater Moment than Ann.

Moment = Force * Perpedicular ...

Draw diagrams to represent the particles in each state: solid, liquid, and gas.

The box for the solid should be an orderly set of circles with no gap between each one. The box for the liquid represents molecules with more energy but not all bonds have been broken. Therefore the box s...
