Which of the following is incorrect about non-uniform circular motion ( \( a_{c}= \) centripetal acceleration, \( a_{t}= \) tangential
\( \mathrm{P} \) acceleration)?

W
(1) \( \vec{v} \cdot \vec{\omega}=0 \)
(2) \( \vec{a}_{c} \cdot \vec{v}=0 \)
(3) \( \vec{\omega} \cdot \vec{a}_{c}=0 \)
(4) \( \vec{v} \cdot \vec{a}_{t}=0 \)
