Interpreting Speed vs Time Graphs

What should you always check first when analyzing a motion graph?

• The legend

• The x-axis

• The title

• The y-axis

On a speed vs. time graph, what does a line pointing upwards indicate?

• Speeding up

• Constant speed

• Standing still

• Slowing down

If a line on a speed vs. time graph is flat, what does it mean?

• The object is moving at a constant speed

• The object is standing still

• The object is slowing down

• The object is speeding up

How do you calculate speed using the speed formula?

• Speed = Time / Distance

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Time x Distance

What is the speed of an object that travels 2 meters in 8 seconds?

• 4 meters per second

• 2 meters per second

• 0.5 meters per second

• 0.25 meters per second

On a distance vs. time graph, what does a flat line indicate?

• The object is moving at a constant speed

• The object is slowing down

• The object is speeding up

• The object is standing still

What does a downward sloping line on a distance vs. time graph represent?

• Standing still

• Moving backward at a constant speed

• Slowing down

• Speeding up

On a speed vs. time graph, what does a downward sloping line indicate?

• Slowing down

• Standing still

• Moving backward at a constant speed

• Speeding up

If the speed of an object decreases from 5 meters per second to 2 meters per second over 3 seconds, what is happening?

• The object is standing still

• The object is speeding up

• The object is slowing down

• The object is moving at a constant speed

What does a flat line on a speed vs. time graph mean?

• The object is slowing down

• The object is speeding up

• The object is moving at a constant speed

• The object is standing still
