Why is understanding one-dimensional motion important in the study of physics?

Multiple Choice

What is the main purpose of using a QR code reader in this learning session?

• To access additional learning resources such as example problems and notes

• To play games related to physics

• To submit homework assignments

• To communicate with classmates

Multiple Choice

Which of the following best describes a vector quantity?

• A quantity that has only a magnitude (number or value)

• A quantity that has both a magnitude and a direction

• A quantity that has only a direction

• A quantity that has neither magnitude nor direction

Multiple Choice

Which of the following statements is true about scalar and vector quantities?

• Scalars have both magnitude and direction, while vectors have only magnitude.

• Scalars have only magnitude, while vectors have both magnitude and direction.

• Both scalars and vectors have only direction.

• Both scalars and vectors have only magnitude.

Multiple Select

Which of the following are scalar quantities? Select all that apply.

Explain the difference between distance and displacement using your own words.

Open Ended

Based on Jim's journey, what is the total distance he traveled and what is his displacement?

Multiple Choice

What is the difference between distance and displacement based on Cindy's and Jim's journeys?

• Distance is the total path traveled, displacement is the shortest path from start to end.

• Distance is always less than displacement.

• Displacement is the total path traveled, distance is the shortest path from start to end.

• Distance and displacement are always equal.

Open Ended

Explain why the displacement can be zero even if the distance traveled is not zero. Give an example.

Multiple Choice

Which of the following scenarios would result in the distance covered being greater than the magnitude of displacement?

• Walking in a straight line from home to school.

• Running around a circular track and stopping at the starting point.

• Driving directly from one city to another without any detours.

• Flying in a straight path from one airport to another.

Open Ended

Describe a real-life situation where the average speed and average velocity of a moving object are different. Explain why this difference occurs.

Multiple Select

Select all statements that are true about velocity.

• Velocity can be positive or negative.

• Velocity is always positive.

• Velocity is the ratio of displacement and time.

• Velocity depends on direction.

Open Ended

What is the difference between speed and velocity? Use the examples of Cindy running toward the ice cream truck and Jim running away from the spider to support your answer.

Multiple Choice

Which of the following best describes the average speed of Jim during his entire trip to the bus stop and back home?

• 0.319 m/s west

• 0.96 m/s

• 1.5 m/s

• 2.0 m/s

Multiple Select

Select all the correct statements about average speed and velocity from the examples of Cindy, Jim, and Harry.

• Average speed is always equal to the magnitude of average velocity.

• Average velocity can be zero even if average speed is not zero.

• Average speed depends only on total distance traveled, not direction.

• Average velocity depends on displacement and direction.

Open Ended

Explain why Cindy’s average velocity is different from her average speed when she finishes the 5k race.

Multiple Choice

Cindy runs a 5k (5000 meters) loop at a speed of 4.3 meters/second. About how long does it take her to finish the race?

• 1162.8 seconds

• 500 seconds

• 1000 seconds

• 4300 seconds

Multiple Choice

What is the average sprint velocity for Jim's run of 100 meters in 13.2 seconds?

• 7.58 m/s

• 6.25 m/s

• 8.33 m/s

• 5.00 m/s

Open Ended

Explain why the average speed for a trip with equal distances at different speeds is less than the arithmetic mean of the two speeds, using the example of driving 4 miles at 30 mi/h and 4 miles at 50 mi/h.

Multiple Choice

Which member of the relay team ran the slowest, and what was their speed?

• Cindy: 8.7 m/s

• Harry: 7.81 m/s

• Kiki: 7.2 m/s

• Jim: 8.06 m/s

Open Ended

Compare and contrast the concepts of speed and velocity using examples from the relay race and Jim’s trip home after the race.

Multiple Choice

What was Jim’s average speed (in m/s) during his 8-minute trip home after the race, given that he walked 0.5 miles at 2.1 m/s and biked 0.5 miles before getting a flat tire?

• 3.35 m/s

• 2.1 m/s

• 4.5 m/s

• 8.29 m/s
