kinematics quantities: position, velocity, acceleration\ A object is constrained to move on a track. The track is shown with several straight segments and several curves. For example, points

A

and

C

are on straight segments. Point

B

is on a circular curve. We do not know what the object is doing. We only know the object must stay on the track.\ The "direction key" shows eight arrow directions labeled 1 to 8 . To use the "direction key", consider the vector mentioned in each question. Match the direction of the vector with the arrow in the key that best shows the direction of the required vector.\ For example, if the object is at point A and the object is moving up, then the "velocity" of the object matches " 1 " in the direction key Choose " 0 " if the vector has a zero magnitude and therefore no direction. For example, if the object was at rest at point

C

, then it would not have a velocity so you match the velocity direction to " 0 " in the key.
