[BMWPower06]

In uniform circular motion:
True False Displacement is constant.
True False Velocity is constant.
True False Acceleration and velocity are perpendicular.
True False Speed is constant.
True False acceleration direction is constant.
True False Acceleration magnitude is constant.


My answers are in bold, the computer says its wrong, can anyone steer me in the right direction?

Thanks :)

Acceleration direction is constant ?

oh, is that the only one i got wrong? i know I am close, the thing doesn't tell me what is wrong/right tho.

Acceleration is always towards the center of the circle, so its direction is changing as the body moves along the circular path
