MATHS - Graphs - Distance Time Graphs

The video tutorial explains distance-time graphs using Sam's cycling journey. It covers how to interpret different lines on the graph, calculate speed using the gradient, and understand the significance of curved lines for acceleration and deceleration. The tutorial emphasizes the relationship between the steepness of the graph and speed, and how direction is indicated by the line's orientation.

What does a straight line on a distance-time graph indicate about Sam's speed?

• He is accelerating.

• He is traveling at a constant speed.

• He is decelerating.

• He is moving in the opposite direction.

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

• By measuring the width of the graph.

• By counting the number of points on the line.

• By dividing the change in distance by the change in time.

• By measuring the length of the line.

If the change in distance is 10 kilometers and the change in time is 0.5 hours, what is the speed?

• 20 kilometers per hour

• 10 kilometers per hour

• 5 kilometers per hour

• 15 kilometers per hour

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

• Constant speed

• No movement

• Acceleration

• Deceleration

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

• No movement

• Acceleration or deceleration

• Travel in the opposite direction

• Constant speed
