Instantaneous Speed Quiz

What is the term used to describe the speed of an object at a specific moment in time?

• Average speed

• Constant speed

• Instantaneous speed

• Variable speed

When calculating instantaneous speed on a distance-time graph, what is the first step?

• Draw a horizontal line

• Draw a tangent to the curve

• Find the midpoint of the curve

• Calculate the area under the curve

In the example of calculating speed at Point A, what is the change in the y-axis?

• 1.8 meters

• 0.75 meters

• 2.5 meters

• 3.7 meters

What is the calculated instantaneous speed at Point B?

• 1.4 meters per second

• 2.8 meters per second

• 3.5 meters per second

• 2.0 meters per second

Why is it important to have distance on the y-axis and time on the x-axis when calculating speed?

• To avoid negative values

• To make the graph look better

• To accurately calculate the slope

• To ensure the graph is symmetrical
