2/5 10Good exercise into understanding position, velocity, an acceleration graphs. Reinforces the description process.

Moving Man Observations

Positive initial velocity, zero acceleration:

Position increases at steady rate.

Velocity stays at a constant rate.

Acceleration remains at 0

Positive initial velocity, positive acceleration:

Position increases at increasing rate.

Velocity increases at steady rate.

Acceleration remains constant positive.

Positive initial Velocity, negative acceleration :

Position increases at decreasing rate, hits inflection point, decreases at a increasing rate.

Velocity decreases at steady rate.

Acceleration remains constant negative.

Zero initial velocity, positive acceleration:

Position increases at increasing rate.

Velocity increases at constant rate.

Acceleration remains constant positive.

Zero initial velocity, negative acceleration:

Position decreases at increasing rate.

velocity decreases at constant rate.

Acceleration remains constant negative.

Negative initial velocity, positive acceleration:

Position decreases at a decreasing rate, hits inflection point, then increases at increasing rate.

velocity increases at steady rate.

Acceleration remains constant positive.

Negative initial velocity, negative acceleration:

position decreases at increasing rate.

Velocity decreases at steady rate.

Acceleration constant at negative.

Negative initial velocity, zero acceleration:

Position increases at steady rate.

Velocity constant positive.

Acceleration at 0."
