The definition of speed is

• $\left|v\right|$

• $vt+v_0$

• $x\left(t\right)$

• $a\left(t\right)$

A particle changes direction when _____ and the sign of  $v\left(t\right)$  changes

•  $v\left(t\right)=0$  

•  $a\left(t\right)=0$  

•  $x\left(t\right)$  

To determine if a particle is speeding up or slowing down at time  $r$   , the first thing you need to do is

• Find

   $v\left(r\right)$   and   $a\left(r\right)$  

• Compare the signs to determine if they are the same or opposite

• Make a sign chart for  $v\left(t\right)$  

• Make a sign chart for  $a\left(t\right)$
