Distance-Time Graphs

Why are distance-time graphs commonly used in physics?

• To show how much time has passed during an event

• To visualize how an object’s speed changes over time

• To show the relationship between distance and time for an object’s motion

• To predict the mass of an object

What does the slope represent on a distance-time graph?

• The object's acceleration

• The object's position

• The object's speed

• The time taken for the object to travel

Which situation might this graph describe?

• Driving to raleigh, stopping, and coming back home.

• Running a mile, taking a break, running back home

• Running part way across a football field, picking up a football, running back to the start

• Biking to a friends house, stay the night, bike back home.

What does a horizontal line on a distance-time graph represent?

• The object is moving at a constant speed

• The object is speeding up

• The object is at rest

• The object is changing direction

In a distance-time graph, what does a steeper line indicate?

• The object is moving at a slower speed

• The object is moving faster

• The object is at rest

• The object is moving at a constant speed

On a distance-time graph, what does a straight line with a positive slope represent?

What can you infer about an object when the distance-time graph shows a line with a shallow slope?

• The object is moving very fast

• The object is moving very slowly

• The object is at rest

• The object is accelerating

Which of the following best defines a dependent variable?

• A variable that is deliberately changed or manipulated in an experiment.

• A variable that remains constant throughout an experiment.

• A variable whose value depends on changes in another variable.

• A variable that is not measured or observed in an experiment.
