Understanding Velocity-Time Graphs

What is plotted on the vertical axis of a velocity-time graph?

• Time

• Distance

• Acceleration

• Velocity

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

• Acceleration

• Distance traveled

• Velocity

• Time

How can you calculate the distance traveled from a velocity-time graph?

• By counting the number of squares

• By measuring the height

• By finding the gradient

• By calculating the area under the graph

What is the acceleration if the velocity increases from 0 to 10 m/s in 4 seconds?

• 2.5 m/s²

• 10 m/s²

• 4 m/s²

• 5 m/s²

How do you find the gradient of a velocity-time graph?

• By measuring the width

• By counting the number of lines

• By dividing the change in velocity by the change in time

• By measuring the area

What is the deceleration if the velocity decreases by 5 m/s over 1 second?

• 2.5 m/s²

• 5 m/s²

• 1 m/s²

• 10 m/s²

How do you estimate acceleration at a specific point on a curvy velocity-time graph?

• By using a ruler

• By drawing a tangent line

• By counting the grid squares

• By measuring the area

What is the purpose of drawing a tangent on a velocity-time graph?

• To measure time

• To estimate the gradient at a point

• To find the area

• To calculate distance

If a tangent line goes across 7 units and up 8 units, what is the gradient?

• 0

• 1

• 7/8

• 8/7

What does a negative gradient on a velocity-time graph indicate?

• Constant speed

• Deceleration

• Acceleration

• No movement
