Physics Unit 1 B- Motion P. 2

Question 1

When two objects with different masses fall, which one hits the ground first?

Answer 1

Both fall at the SAME time

Question 2

proportionalities between Air time, max height and range for a launch angle of 45*

Answer 2

Air time = moderate
max height = moderate
Max range

Question 3

trajectory

Answer 3

path that projectile follows

Question 4

Range

Answer 4

horizontal displacement

Question 5

Launch’s angle is 45 degrees

Answer 5

Maximum Range
Average Max Height

Question 6

Launch’s angle is MORE than 45 degrees

Answer 6

Smaller range (Vx is lower)
Highest Max Height (90*)

Question 7

Launch’s angle is LESS than 45 degrees

Answer 7

greater Vx compared to Vy
Low max height since low Vy

Question 8

proportionalities for airtime, max height and range for an angle over 45* (less say 90*)

Answer 8

Max airtime
Max height
Lowest range (0 for 90*)

Question 9

What happens to the max height with horizontal wind resistance?

Answer 9

STAYS THE SAME

Question 10

What happens to the range with a projectile motion consisting horizontal wind resistance?

Answer 10

The range decreases

Question 11

Which one lands first to the ground: an object that drops with a vertical or horizontal launch ?

Answer 11

BOTHHHHH

Question 12

If acceleration is slowing down, algebraically what would be added?

Answer 12

A negative (-)

Question 13

How do we show an object falling algebraically?

Answer 13

A negative sign (-)
