Exploring Motion Graphs

What is the primary purpose of a position-time graph?

• To measure the weight of an object

• To illustrate the distance an object travels over time

• To determine the color of an object

• To calculate the volume of an object

What units are typically used on a distance vs. time graph?

• Kilograms and minutes

• Meters and seconds

• Liters and hours

• Miles and pounds

What does a straight diagonal line on a distance vs. time graph indicate?

• The object is at rest

• The object is accelerating

• The object is traveling at a constant speed

• The object is decelerating

Which object is traveling the fastest if it has the steepest slope on a distance vs. time graph?

• Object B

• Object A

• Object C

• Object D

What does a horizontal line on a distance vs. time graph indicate?

• The object is decelerating

• The object is moving backward

• The object is accelerating

• The object is at rest

How do you calculate the average speed of an object on a distance vs. time graph?

• Distance initial minus distance final divided by time initial minus time final

• Distance initial plus distance final divided by time initial plus time final

• Distance final plus distance initial divided by time final plus time initial

• Distance final minus distance initial divided by time final minus time initial

Which object traveled at the greatest average speed?

• Object D

• Object C

• Object A

• Object B

Which object traveled at the slowest average speed?

• Object A

• Object B

• Object C

• Object D

What is the average speed of an object if it travels 60 meters in 30 seconds?

• 2 meters per second

• 4 meters per second

• 1 meter per second

• 3 meters per second

Which type of line on a distance vs. time graph indicates acceleration?

• Vertical line

• Curved line

• Horizontal line
