A runner completes one full 400 m lap and finishes where they started.
✅ Answer: 0 m
What is the major difference between speed and velocity?
✅ Answer: Velocity includes direction.
🧠 VELOCITY = SPEED + DIRECTION
A car changes velocity from 10 m/s to 30 m/s in 5 seconds.
What is its acceleration?
(30 − 10) ÷ 5
20 ÷ 5 = 4
✅ Answer: 4 m/s²
A student walks 12 m east and 5 m west.
Give BOTH:
Distance = ?
Displacement = ?
Distance:
12 + 5 = 17 m
Displacement:
12 − 5 = 7 m EAST
✅ Answer: Distance = 17 m; Displacement = 7 m EAST
A runner completes two 400 m laps. What distance did the runner travel?
400 × 2 = 800 m
✅ Answer: 800 m
A student walks:
20 m north → 8 m south → 5 m north
What is the displacement?
20 − 8 + 5 = 17
Which represents velocity?

C. Velocity includes direction. ✅
Chief Keef travels 15 m west, 10 m east, 20 m west, and 5 m east. What is his total distance?
15 + 10 + 20 + 5 = 50 m
✅ Answer: 50 m
Chief Keef travels:
30 m west → 10 m east → 5 m west
What is his displacement?
30 − 10 + 5 = 25
✅ Answer: 25 m WEST
A runner travels 240 m in 8 seconds toward the north. What is the runner's velocity?
240 ÷ 8 = 30
✅ Answer: 30 m/s NORTH
