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

Part 1:
- a. distance; b. time
- velocity
- Constant
- average
- Displacement is the straight-line measurement of the change in position of an object from its starting point to its ending point, including direction.
- 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:
