[24] Unit 8 Physics Concept Check Vats

What is the distance and displacement from the house to the factory?

• Distance = 200m, Displacement = 120m
• Distance = 120m, Displacement = 200m
• Distance = 320m, Displacement = 80m
• Distance = 80m, Displacement = 320m

Lucinda walked 400m west from her house to the school. She then walked 200m east to the store. What is her distance? Include units.

Lucinda walked 400m west from her house to the school. She then walked 200m east to the store. What is her displacement? Include units.

(a)  

Which of the following is TRUE about speed or velocity?

• Speed and velocity both include the direction (North West East South, + or -)
• Velocity = displacement ÷ time
• Velocity is how much your speed changes during a period of time
• Speed = time ÷ distance

Liam starts walking at point A and gets to point D in 26 minutes. What is his speed? Include units.

(a)  

The table shows the motion data for two objects during two trials of an investigation. Which object travels at the greater average speed?

• Object 1, because it travels a greater distance per unit of time
• Object 1, because it travels the longer amount of time
• Object 2, because it travels the shorter amount of time
• Object 2, because it travels the shorter distance per unit of time

Two students record the distance they each traveled in 60 seconds in the data table shown. What is the speed of each student?

• Student 1 = 0.66m/s , Student 2 = 0.33m/s
• Student 1= 1.5m/s , Student 2 = 3m/s
• Student 1= 2m/s , Student 2 = 1m/s
• Student 1 = 2m/s , Student 2 = 2m/s

If the students continued at the same speed from the last question, what is the total distance they have walked after another 30 seconds (90 seconds total)?

• Student 1 traveled 40m and student 2 traveled 20m
• Student 1 traveled 50m and student 2 traveled 30m
• Student 1 traveled 60m and student 2 traveled 30m
• Student 1 traveled 70m and student 2 traveled 25m

This graph shows the distance an object traveled in 11 seconds. Which answer choice best describes the movement of the object between the times of 0 and 6 seconds on the graph?

• Moving at a constant speed
• Moving towards the north
• Accelerating
• Stopped
