There is one kind of ski equipment that
applies the principles of slope and inertia.
It’s the ramp for the ski jump at the Winter
Olympics. It is a long and steep ski slope. At the
end of the slope is a kicker ramp. When you watch a ski
jumping competition and its equipment on TV, you may find
that it’s exciting. However, if you saw all of this in person, you
may freak out, especially if you stood on the starting platform and looked
down the mountain. Skiers first go down a take-off ramp. Once they
reach the kicker ramp, they fly off of the ramp and are projected forward
through the air by the movement of inertia. Finally, they travel and land in
the shape of a parabola. The champion is the one who jump the furthest.
When driving on roads that aren’t flat, what do you feel?

The a deck of an aircraft carrier is not completely flat. The flight deck is
inclined like a ramp for jets to take off of. The design of a carrier’s deck is no
different from an ordinary boat. There’s no need for any special equipment,
hence, there is no need to enlist any professional or technical staff. Of course,
as a flight deck, its strength must be enhanced.
When planes are carrying out their flight
mission, the planes speed up near the end
of the ramp deck. This creates an upwards
lift, which increases the elevating force
needed for taking off. The movement of
inertia helps the plane take off from the
ramp.
Kids, aside from the slanted deck of aircraft
carriers, where else are the principles of
the ski-jump ramp applied?
