Question 1

as mass increases range

Answer 1

RTS

Question 2

as mass increases max ht

Answer 2

RTS

Question 3

as mass increases time of flight

Answer 3

RTS

Question 4

the effect of mass is counterintuitive because

Answer 4

It’s hard for us to imagine throwing different mass projectiles at the same speed

Question 5

as angle increases the time in the air

Answer 5

increases

Question 6

as angle increases the max height

Answer 6

increases

Question 7

as angle increases the range

Answer 7

increases to 45° then decreases

Question 8

the rule for matching ranges is

Answer 8

2 angles that add up to 90°(complimentary) have the same range

Answer 13

decreases

Question 14

as air resistance increases, the time in the air

Answer 14

decreases

Question 15

as air resistance increases, the max height

Answer 15

decreases

Question 16

as launch velocity increases, time in the air

Answer 16

increases

Question 17

as launch velocity increases, the max height

Answer 17

Question 18

as launch velocity increases, the range

Answer 18

increases

Question 19

if we double the launch velocity, the range will

Answer 19

increase 4x

Question 20

if we triple the launch velocity, the range will

Answer 20

increase 9x

Question 21

if we quadruple the launch velocity the range will

Answer 21

increase 16x

Question 22

if we halve the launch velocity, the range will

Answer 22

decrease to 1/4x

Question 23

the range is a function of the launch velocity ….

Answer 23

squared
