Understanding Velocity and Speed Graphs

What does a speed-time graph show?

• Speed on the vertical axis and time on the horizontal axis

• Velocity on the vertical axis and time on the horizontal axis

• Distance on the vertical axis and time on the horizontal axis

• Acceleration on the vertical axis and time on the horizontal axis

Why is a velocity-time graph preferred over a speed-time graph?

• It does not require a horizontal axis

• It is easier to draw

• It allows calculation of displacement and acceleration

• It can show negative speed

What is the significance of the area under a velocity-time graph?

• It shows the object's acceleration

• It measures the object's time

• It represents the object's speed

• It indicates the object's displacement

How can you find an object's instantaneous velocity?

• By calculating the slope of a speed-time graph

• By reading the coordinates of a velocity-time graph

• By measuring the distance traveled

• By timing the object's motion

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

• No motion

• Constant speed

• Nonuniform acceleration

• Uniform acceleration
