Translational Motion

Question 1

distance vs. displacement

Answer 1

distance = scalar
displacement  = vector

Question 2

any change in velocity is ____

Answer 2

acceleration (in either magnitude or direction)

Question 3

linear motion equations

Answer 3

detla x = v(i)t + 1/2at^2
delta v = at
v(f)^2 = v(i)^2 +2a delta x

Question 4

v(average) =

Answer 4

1/2(v(f) + v(i))

Question 5

peak height of projectile motion equation

Answer 5

v(i)sin(theta) = sqrt(2gh)

Question 6

___ of a projectile affect drag

Answer 6

shape, surface area, velocity

Question 7

mass and air resistance…

Answer 7

mass doesn’t change force of air resistance, does change path of projectile experiencing the resistance
larger masses experience less deceleration due to air resistance because they are less affected by the same force of resistance
