Kinematics
Describe motion with position, velocity, and acceleration before asking what causes it.
one-dimensional motionx = x₀ + v₀t + ½at²
Kinematics describes what motion does. It does not explain the force that produced the acceleration:that is the boundary between this model and dynamics.
position21.0 m
velocity10.0 m/s
acceleration2.0 m/s²
Position is the accumulated story of velocity; velocity is the accumulated story of acceleration. Their graph slopes are related, not interchangeable.

Use the model, then answer without looking back. Each check isolates one decision a learner should be able to make after this lesson.
