Exploring Distance-Time Graphs and Speed Concepts

Why is it important not to confuse distance-time graphs with speed-time graphs?

• They have the same calculations.

• They look exactly the same.

• Confusing them can lead to losing easy marks in exams.

• They are used for different subjects.

What is the first step in plotting Bob's journey on a distance-time graph?

• Start at 0 meters and 0 seconds.

• Start at 50 meters and 10 seconds.

• Start at 70 meters and 30 seconds.

• Start at 100 meters and 35 seconds.

How long did it take Bob to cover the first 50 meters?

• 10 seconds

• 5 seconds

• 30 seconds

• 20 seconds

What is the formula to calculate speed?

• Speed = Distance + Time

• Speed = Distance / Time

• Speed = Distance x Time

• Speed = Time / Distance

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

• Bob is moving at a constant speed.

• Bob is accelerating.

• Bob is decelerating.

• Bob is not moving.

What should you do if you want to learn about speed-time graphs and acceleration?

• Watch the next video.

• Read a textbook.

• Ask a friend.
