Velocity-Time Graph Concepts

The video tutorial covers real-life graphs, focusing on distance-time and velocity-time graphs. It explains how to identify the steepest sections on a distance-time graph to determine speed, and how to calculate average speed. The tutorial also discusses velocity-time graphs, highlighting the concept of acceleration and how to find when acceleration is zero. Additionally, it demonstrates how to calculate distance using the trapezium rule on a velocity-time graph.

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

• The object is moving backwards.

• The object is stationary.

• The object is moving faster.

• The object is moving slower.

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

• Subtract time from distance.

• Multiply distance by time.

• Divide distance by time.

• Add distance and time.

What is the formula for average speed?

• Total distance multiplied by total time.

• Total time minus total distance.

• Total time divided by total distance.

• Total distance divided by total time.

In a velocity-time graph, what does a horizontal line indicate about acceleration?

• Acceleration is zero.

• Acceleration is decreasing.

• Acceleration is increasing.

• Acceleration is constant but not zero.

What is the significance of the gradient in a velocity-time graph?

• It represents speed.

• It represents distance.

• It represents acceleration.

• It represents time.

When is the acceleration zero in a velocity-time graph?

• When the line is vertical.

• When the line is horizontal.

• When the line is curved.

• When the line is at a 45-degree angle.

What does a turning point in a velocity-time graph indicate?

• An increase in speed.

• A constant speed.

• A change from positive to negative acceleration.

• A stationary object.

What does the area under a velocity-time graph represent?

• The speed of the object.

• The time taken by the object.

• The distance traveled by the object.

• The acceleration of the object.

How can you determine the total distance traveled using a velocity-time graph?

• By counting the number of peaks in the graph.

• By measuring the height of the graph.

• By finding the area under the graph.

• By calculating the slope of the graph.

What is the formula for the area of a trapezium used in velocity-time graphs?

• Base times height.

• Half the sum of parallel sides times height.

• Base plus height.

• Sum of all sides.
