If an object of interest interacts with several other objects, the net force is the vector sum of the individual forces. Projectile motion and circular motion are both included in AP Physics 1.
Newton’s Second Law states, “The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.”
Key Concept: Net Force - the vector sum of all forces acting on a particle or body
Free-body diagrams are useful tools for visualizing forces being exerted on a single object and writing the equations that represent a physical situation.
As we’ve covered over a multitude of standards in this guide, you must understand how to correctly depict a free-body diagram in AP Physics 1. This includes the few key concepts that we’ve dealt with. If you remember two key things with free-bodies, keep in mind they only show external forces (ie. forces that cause motion) and do not draw components unless otherwise specified.
