Using physics, relate a roller coaster, a super bouncy ball, and a pendulum to each other.
Don't you just love science?

They convert potential energy to kinetic energy to potential energy.
Back and forth

The weight varies according to the motion, weighing more at the bottom of a trajectory and less at the top.
A pendulum will only break its string at the lowest point of its swing, the load becoming weightless at the top just for a moment as it changes direction. A ball is weightless at the top of its bounce, and so is a roller-coaster at the top of its curve: if it is carried over to start a further fall then the upward momentum must be enough to counteract all of the gravity acting on it.

If there is no one else in the theme park, i don't think i'd wear a jilbab (don't wear one anyway, but you know). And if you're gonna say something like 'the ride operator would be there' then i guess as soon as i get into the roller coaster i'd tuck the loose parts behind me and sit on most of the jilbab =P And i mostly wear two-piece headscarves anyway so yeah.

Well,...if you put yours all the way "in", and start pushing it in and out like a pendulum with your bouncy balls banging off her butt with the rhythm, you'll both have a super fun ride....better than any damn roller coaster!

With out gravity, none of them would work.

Also think wave motion and momentum.
