Final answer:
To draw additional velocity vectors, maintain the same length for horizontal vectors when there is no horizontal acceleration and adjust the length for vertical vectors due to gravity. Draw vectors head-to-tail, using correct direction and magnitude for an accurate representation of motion.
Step-by-step explanation:
To finish the image by drawing more vertical and horizontal velocity vectors, you should consider the behavior of the objects in motion and the forces acting on them. In instances where there is no acceleration in the horizontal direction, horizontal velocity vectors remain the same length, because the horizontal velocity is constant. In contrast, vertical velocity vectors may change length due to the effects of gravity causing vertical acceleration.
Following the instructions on how to construct vectors:
- Select a vector and draw it to scale, ensuring its direction and magnitude are accurate, and place an arrowhead at the tip.
- For subsequent vectors, begin at the head of the previous vector, draw the next vector making sure it is in the correct direction and to scale.
- Continue this process for all the vectors, guaranteeing an accurate representation of their magnitudes and directions.
To correctly represent two-dimensional motion, ensure that the resultant vector starts from the tail of the first vector and ends at the head of the last vector, thus completing the vector addition.
