Constructing Distance-Time Graphs and Analyzing Speed

This video tutorial from freesciencelessons.co.uk teaches how to construct and interpret distance-time graphs. It covers plotting graphs from given data, calculating speed using graph gradients, and using tangents to determine speed for accelerating objects. The video includes examples and exercises for practice, catering to both foundation and higher-tier students.

What is the primary objective of this video tutorial?

• To learn about different types of graphs

• To construct and analyze distance-time graphs

• To understand the concept of velocity

• To explore the history of graph theory

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

• The object is accelerating

• The object is moving at a constant speed

• The object is stationary

• The object is moving backward

How do you represent a stop in movement on a distance-time graph?

• A curved line

• A vertical line

• A horizontal line

• A diagonal line

What is the first step in plotting a distance-time graph?

• Calculate the speed

• Place a dot at the starting point

• Connect the dots with lines

• Draw the axes

What does the gradient of a distance-time graph represent?

• The time taken

• The distance traveled

• The object's acceleration

• The object's speed

How do you calculate speed from a distance-time graph?

• Subtract time from distance

• Divide distance by time

• Add distance and time

• Multiply distance by time

What is the speed of an object if it travels 120 meters in 60 seconds?

• 3 meters per second

• 4 meters per second

• 1 meter per second

• 2 meters per second

For higher-tier students, what is used to determine the speed of an accelerating object?

• A horizontal line

• A diagonal line

• A tangent

• A vertical line

What does an upward-sloping curve on a distance-time graph indicate?

• Stationary object

• Constant speed

• Deceleration

• Acceleration

How do you find the speed at a specific point on a curve in a distance-time graph?

• Measure the curve's length

• Draw a tangent and calculate its gradient

• Draw a vertical line

• Draw a horizontal line
