When applying the equations of kinematics for an object moving in one dimension, which of the following statements must be true?

The velocity of the object must always be in the same direction as its acceleration. (Select all that apply)

The acceleration of the object must remain constant.

The velocity of the object must remain constant.

The position of the object must increase with time.

The velocity of the object must increase with time.

Step 1

Equations of kinematics for an object moving in one dimension are constructed from the fact that the acceleration of the object is constant. Constant acceleration implies velocity changes with time. Velocity can either increase or decrease with time.

Step 2

Position of the object may increase or decrease with time. Direction ...
