Understanding Speed and Velocity from Graphs

What is the significance of labeling the positive direction on a graph?

• It helps in identifying the origin.

• It indicates the direction of motion.

• It is used to measure time intervals.

• It is necessary for calculating speed.

When drawing a position-time graph, what increments are used on the vertical axis?

• 200 meters

• 300 meters

• 100 meters

• 50 meters

How is the slope of a position-time graph related to velocity?

• It represents the acceleration.

• It is equal to the average velocity.

• It indicates the time taken.

• It shows the total distance traveled.

What does a constant slope on a position-time graph indicate?

• Increasing acceleration

• Decreasing speed

• Constant velocity

• Changing velocity

In a velocity-time graph, what does a horizontal line represent?

• Constant velocity

• Constant acceleration

• Changing speed

• Zero velocity

What is the constant velocity for the first 200 seconds in the given graph?

• 2.0 meters per second

• 1.5 meters per second

• 1.0 meters per second

• 0.5 meters per second

How can displacement be determined from a velocity-time graph?

• By counting the number of peaks

• By finding the midpoint of the graph

• By measuring the slope

• By calculating the area under the graph

What geometric shape is used to calculate the area under a velocity-time graph?

• Triangle

• Rectangle

• Circle

• Trapezoid

What is the displacement if the area under the velocity-time graph is 300 square units?

• 400 meters

• 100 meters

• 200 meters

• 300 meters

What equation relates average velocity, displacement, and time?

• v = d/t

• d = v * t

• t = d/v

• v = t/d
