Explore the critical concepts of distance and displacement through real-world examples, such as Billy running laps around a track. We highlight how displacement can often be different from total distance traveled, emphasizing the distinction between these two terms using practical problems. Additionally, we delve into speed and velocity calculations, providing practice problems to solidify understanding. Whether it's calculating the average speed of a race car or determining how long various journeys will take, this review is designed to enhance your grasp of motion.

Distance vs. Displacement Billy runs 3 full laps around the track. If each lap is 400 m, what is his displacement?
Distance vs. Displacement Billy runs 3 full laps around the track. If each lap is 400 m, what is his displacement? displacement = 0 m
Distance vs. Displacement Billy runs 1 full lap around the track. If each lap is 400 m, what is his total distance traveled?
Distance vs. Displacement Billy runs 1 full lap around the track. If each lap is 400 m, what is his total distance traveled? distance = 400 m
Graphing Distance vs. Time What is the total distance traveled at 55s?
Graphing Distance vs. Time How long did it take to travel 40m?
Graphing Distance vs. Time What is happening between 20s and 48s?
Calculating Speed & Velocity V = d t V = velocity or speed (m/s) d = distance (m) t = time (s)
Calculating Speed & Velocity V = d t Rearrange the formula to solve for distance.
Calculating Speed & Velocity V = d t Rearrange the formula to solve for time.
