Understanding velocity-time graphs in kinematics

Forces and motion • Speed, acceleration, and laws of motion

Key concepts

What you'll likely be quizzed about

  • A velocity-time graph displays velocity on the y-axis and time on the x-axis.
  • The slope of the graph indicates acceleration.
  • A straight line shows uniform acceleration, while a horizontal line means constant velocity.
  • Graphs can also have negative slopes, indicating deceleration.

What does a horizontal line on a velocity-time graph represent?

Click to reveal answer

A horizontal line represents constant velocity.

Key notes

Important points to keep in mind

The steeper the slope, the greater the acceleration.

For curved sections, use integration to find areas.

Always label axes correctly on graphs.
