Uniform Motion Lab

Choose an experiment

Mission

Set a starting position and constant velocity. Run the rover and test whether equal times produce equal position changes.

What the result means

At constant velocity, every additional second changes position by the same amount.

Learning objectives

  • Recognize equal distances in equal time intervals.
  • Relate position, time, velocity, and displacement.
  • Interpret the slope of a position–time graph.
  • Compare uniform and accelerated motion.
  • Predict a later position from initial position, velocity, and time.

Key concepts demonstrated

Uniform motion has constant velocity. Its timed position markers are equally spaced, and its position–time graph is a straight line. A greater constant velocity produces a steeper line.

Suggested experiments

  • Set velocity to its maximum and observe marker spacing.
  • Set velocity to zero and interpret the horizontal graph.
  • Use a negative velocity and watch position decrease.
  • Compare constant speed with positive acceleration.

Questions for exploration

  • Can an object be moving uniformly while travelling slowly?
  • What does a horizontal position–time graph mean?
  • How does doubling velocity change arrival time?
