Learning Targets

9) Students should be able to analyze situations in which a particle remains at rest, or moves with constant velocity, under the influence of several forces.

(10) Calculate, for an object moving in one dimension, the velocity change that results when a constant force F acts over a specified time interval.

(11) Determine, for an object moving in a plane whose velocity vector undergoes a specified change over a specified time interval, the average force that acted on the object.

(12) Draw a well-labeled, free-body diagram showing all real forces that act on the object.
