What is the vertical velocity
of a skater at the top of a jump? Why is it important to know the vertical
velocity at this point in time?
What forces are acting on a skater
while in the air, and in which direction do they act?
Knowing what you know about forces
acting in the horizontal direction during flight and Newton's first law, what
is the horizontal velocity at landing for any projectile?
Why is the path of a skater's
jump in the shape of a parabola?
When calculating jump distance
do you use time-up or total time?
Is the total time of a jump always
twice the time-up? Why or Why not?
What is the name of the technique
for calculating vertical and horizontal velocity from resultant velocity?
Does this technique only work for velocity or do you think it would work for
any vector, such as force or displacement?
In what other instances could
you use the two basic formulas we gave you:
Are they only useful for projectile
motion problems?
