P01 - Kinematics and Free Fall Test Review

#1

• v_f = v_i + at

• Δd = v_it + ¹/₂at²

• v_f² = v_i² + 2aΔd

• v = Δd/t

• s = d/t

#2

• vi

• a

• vf

• t

• Δd

#4 (a)

• change in velocity over time

• change in distance over time

• change in acceleration over time

• change in displacement over time

#4 (b)

• speeding up

• slowing down

• gravity

• displacement

• constant velocity

#5

• -9.81 m/s²

• 9.81 m/s²

• 0 m/s²

• 9.81 m/s

#6

• down; with a negative

• down; with an arrow going down

• up; with a negative

• up; with a positve

• we need to read the problem before we decide which direction gravity goes

#7 (a)

• vf = 0 m/s

• vi = 0 m/s

• Δd = 0 m

• t = 0 s

• a = 0 m/s²

#7 (b)

• vf = 0 m/s

• vi = 0 m/s

• Δd = 0 m

• t = 0 s

• a = 0 m/s²

#7 (c)

• vf = 0 m/s

• vi = 0 m/s

• Δd = 0 m

• t = 0 s

• a = 0 m/s²

#8

• heavier objects fall faster than lighter objects

• lighter objects can fall faster than heavier objects

• mass has no effect on the free fall acceleration

• objects that are larger fall faster

• objects that are smaller fall faster
