Unit 1 Physics - Position vs Time Graphs

What is the purpose of a line of best fit?

• To connect all data points exactly

• To predict outcomes using existing data points

• To ensure all points are below the line

• To make the graph look symmetrical

How should a line of best fit be drawn in relation to the data points?

• It should pass through all data points

• It should have all points above it

• About half of the points should be above and half below

• It should not touch any points

What can the slope of a position vs time graph tell us about the motion of the object?

• The height of the object

• The speed/velocity of the object

• The weight of the object

• The acceleration of the object

What is the velocity of the object's motion as depicted in the graph?

• 1.33 m/s

• 2.00 m/s

• 0.75 m/s

• 1.00 m/s

An object is recorded to have the motion depicted in the graph, what is the velocity of the object’s motion?

• 6 m/s

• 5 m/s

• 4 m/s

• 3 m/s

What is the velocity of segment A in the position vs time graph?

• 6 m/s

• 0 m/s

• -2 m/s

• 0 m/s

• -4 m/s

Which graph is would represent a decrease in speed?

• Graph A
• Graph B
• Graph C
• The object is not decreasing in speed in any of these graphs

During what period of time was Marie stopped?

• 0-5 minutes

• 5-10 minutes

• 10-25 minutes

• 25-30 minutes

What could account for Marie’s motion at 27 minutes?

• She was late so she broke the speed limit

• She forgot something at home and ran back to get it

• She was stopped at a red light

• She was driving across the top of a hill
