Test your Memory- acceleration

Object starts from rest

• Final velocity = zero

• initial velocity = zero

• acceleration = zero

• Time - zero

Object slows down

• initial velocity = 0

• final velocity = 0

• initial position = 0

• Acceleration = ( - )

Object comes to a stop

• initial velocity= 0

• Final velocity= 0

• initial position = 0

• acceleration = 0

Object moves with constant velocity

• Initial velocity = 0

• Final velocity = 0

• Initial position = 0

• Acceleration = 0

Which variable is given in the following question: ( multi selection )

A) v_i

B) v_f

C) a

D) t

E) x

F) v

• A

• B

• C

• D

• E

Pick the right equation:

what is constantly accelerated from rest to 15 m/s in 5 seconds ?

A-  Vf=Vi+at

1. B- x = vit + ½ at²

2. ^{C -} vf²=Vi² + 2ax

   D- x = ((V; + vf)t

• A

• B

• C

• D
