Explanation:

1. Speed is calculated as distance traveled over time, so the blanks match the word bank terms.
2. Velocity includes both speed and direction, and the statement gives a direction (northeast).
3. Constant speed means covering equal distance in equal time intervals, which clock hands do.
4. Total distance divided by total time gives average speed.
5. Displacement is the straight-line change in position from start to end, including direction.
6. Speed is a scalar (only magnitude), velocity is a vector (magnitude + direction).
7. The speed triangle shows the relationships: speed = distance/time, distance = speed×time, time = distance/speed.
8. Part 3 is incomplete (no graph provided), so it cannot be answered.

Answer:

Part 1:

1. a. distance; b. time
2. velocity
3. Constant
4. average
5. Displacement is the straight-line measurement of the change in position of an object from its starting point to its ending point, including direction.
6. Speed- Distance an object travels per unit of time; Velocity- A vector quantity =The speed and direction of an object’s motion

Part 2:

Speed: $S=\frac{D}{T}$
Distance: $D=S \times T$
Time: $T=\frac{D}{S}$

Part 3:
