2.1 Projectile Motion Flashcards
as mass increases range

as mass increases max ht

as mass increases time of flight
RTS
the effect of mass is counterintuitive because
It’s hard for us to imagine throwing different mass projectiles at the same speed
as angle increases the time in the air
increases
as angle increases the max height
increases
as angle increases the range
increases to 45° then decreases
the rule for matching ranges is
2 angles that add up to 90°(complimentary) have the same range
the maximum time in the air occurs at
90°
the minimum time in the air occurs at
0°
the maximum height occurs at
90°
the maximum range occurs at
45°
as air resistance increases, the range
decreases
as air resistance increases, the time in the air
decreases
as air resistance increases, the max height
decreases
as launch velocity increases, time in the air
increases
as launch velocity increases, the max height
increases
as launch velocity increases, the range
increases
if we double the launch velocity, the range will
increase 4x
if we triple the launch velocity, the range will
increase 9x
if we quadruple the launch velocity the range will
increase 16x
if we halve the launch velocity, the range will
decrease to 1/4x
the range is a function of the launch velocity ….
