Assessment Objectives

• Calculate the kinetic friction acting on a moving object.
• Recognize that forces balance even on moving objects, when the object is moving at constant velocity.
• Use forces to calculate the acceleration of an object.
• Use acceleration to find one or more forces.
• Recognize that objects moving together have the same acceleration.
• Identify the force pairs between two interacting objects, and incorporate them into the appropriate force diagrams. ( Newton's Third Law)
