a_x

• horizontal acceleration

• always 0

a_y

• vertical acceleration

• always gravity (-9.8) during freefall

V_x

• initial velocity

• always # given

V_y

• initial horizontal velocity

• always 0

head-to-tail method

• used to find displacement

• draw given vectors and draw the resultant vector by connecting the tail of the first vector to the head of the last vector

pythagorean therom

• a²+b²=c²

• number value of resultant vector

• when numbers are given and vectors form a right triangle

X value

• horizontal

• independent from y (don’t affect each other)

Y value

• Vertical

• independent from x (don’t affect each other)
