What you’ll practice

Choose a motion model for a new situation

Connect quantities with representations

Compare distance and displacement, read graph slopes, and explain the directions of velocity and acceleration. Identify when equal velocities do not imply equal positions.

Combine stages of a journey

Work through stops, braking, and an accelerate–cruise–brake trip. Keep elapsed time and position consistent across the changes.

Extend motion into two dimensions

Add survey displacements, compare river-crossing strategies, and use horizontal and vertical components in projectile calculations.

A question from this set

Back to the start after a stop

A delivery cart travels away from its starting point, pauses, and returns to that same point. Which statement about the entire trip is correct?

Average velocity and average speed are both zero.
Average velocity is zero, while average speed is positive.
Average speed is zero, while average velocity is positive.

Try it in the practice set

The complete route includes the outbound leg, the pause, and the return.

Key ideas

Start with what the question asks you to measure

Choose totals or components deliberately

Whole-trip speed uses the full path and elapsed time. Average velocity uses the endpoint change. Two-dimensional motion requires separate components that share the same time interval.

Use a model within its conditions

Constant-acceleration equations describe intervals with constant acceleration. The conceptual questions also include a ball approaching terminal speed, where acceleration changes as resistance builds.

Check the connections across the unit

Each question opens its own prepared scenario after you check an answer. Compare motion records across a return journey, a braking cart, a falling sensor, a river crossing, and a projectile launch.

Use a hint for a starting point or open a worked solution to follow the reasoning. Your progress saves in this browser, so you can return to unfinished questions.
