Mission F2D2: Fnet = m•a and Forces at Angles

Mission F2D2 pertains to situations in which an angled force is used to accelerate an object along a horizontal surface -with or without friction. The mission consists of 28 questions organized into 9 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
 

Learning Outcomes

• The student should be able to analyze physical situations in which forces act at angles to the horizontal to accelerate objects across horizontal surfaces.
• The student should be able to determine the horizontal accelerations of objects to which forces are applied at angles to the horizontal.

• If a force is applied at an angle to pull an object across a surface, then how do the normal force and gravity force compare?
• If a force is applied at an angle to pull an object across a surface, then how does one determine the force of friction?
• How can one mathematically analyze a situation in which a force is applied at an angle to accelerate an object across a horizontal surface?
