Position-Time Graphs and Velocity

What does a position-time graph show on the y-axis versus the x-axis?

• Velocity versus time

• Position versus time

• Acceleration versus time

• Force versus time

What is the formula for average velocity (v_avg) in terms of position and time?

• v_avg = Δt / Δx

• v_avg = Δx / Δt

• v_avg = Δx × Δt

• v_avg = Δt - Δx

What does an upward slope on a position-time graph indicate?

• Moving forward

• Stopped

• Moving backward

• Accelerating

What does a horizontal or flat slope on a position-time graph indicate?

• Moving forward

• Stopped

• Moving backward

• Accelerating

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

• Moving forward

• Stopped

• Moving backward

• Accelerating

For the given position-time graph, calculate v_avg from t=0 to t=2s.

• 5 m/s

• 2.5 m/s

• 10 m/s

• 0 m/s

What happens to the magnitude of velocity when the slope of a position-time graph becomes steeper?

• Velocity has higher magnitude

• Velocity has lower magnitude

• Velocity remains constant

• Velocity becomes zero

What happens to the magnitude of velocity when the slope of a position-time graph becomes flatter?

• Velocity has higher magnitude

• Velocity has lower magnitude

• Velocity remains constant

• Velocity becomes zero

What is the box's velocity from 0 to 5 seconds based on the position-time graph?

• 2 m/s

• 1 m/s

• 0 m/s

• -1 m/s
