Understanding Speed and Distance Relationships

The video tutorial covers graphing motion, focusing on distance-time graphs. It provides instructions for setting up a split-screen to work alongside the video. The tutorial explains how to interpret motion graphs, emphasizing the relationship between distance, time, and speed. An exercise involving Ashley's bicycle trip is used to analyze graph data. The video also discusses the relationship between slope and speed, followed by a vocabulary review and assignment instructions.

What should you do first when starting the video tutorial?

• Email the teacher for instructions.

• Open the document and make a copy.

• Watch the entire video before doing anything.

• Start answering the worksheet questions immediately.

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

• The object is moving at a constant speed.

• The object is stationary.

• The object is decelerating.

• The object is accelerating.

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

• The object is stationary.

• The object is moving at a constant speed.

• The object is accelerating.

• The object is moving backward.

How do you calculate the speed of an object using a distance-time graph?

• Add distance and time.

• Divide distance by time.

• Subtract time from distance.

• Multiply distance by time.

During Ashley's trip, what was her constant speed for the first four minutes?

• 100 meters per minute

• 200 meters per minute

• 300 meters per minute

• 400 meters per minute

What was Ashley's average speed for her entire trip?

• 200 meters per minute

• 160 meters per minute

• 100 meters per minute

• 400 meters per minute

What is the definition of velocity?

• The change in speed over time.

• The time taken to travel a distance.

• The total distance traveled.

• Speed in a given direction.

What does a steeper slope on a distance-time graph indicate?

• The object is moving backward.

• The object is stationary.

• The object is moving faster.

• The object is moving slower.

What happens to the speed when the slope of the line on a graph becomes flatter?

• The object moves backward.

• The speed remains constant.

• The speed decreases.

• The speed increases.

What is the relationship between speed, distance, and time?

• Speed is time divided by distance.

• Speed is the sum of distance and time.

• Speed is distance divided by time.

• Speed is distance multiplied by time.
