The motion map shows an object’s position and velocity at given times. how can the map be changed so it shows constant acceleration after the object changes direction? by adding vectors that are all the same length and placing them above the current top row of vectors by adding vectors that gradually increase in length and placing them above the current top row of vectors by adding vectors that are all the same length and placing them below the current bottom row of vectors by adding vectors that gradually increase in length and placing them below the current bottom row of vectors
