B. by Erik Lascaris (erikl@bu.edu) – version 25-Sep-09 1 Subject: Forces (Free Body Diagrams; F = ma) Used for: To find the acceleration of one of more objects when they feel one or Newton's Second Law of Motion states that 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. The Answer comes out to be 12.22 Joules. When an object all of a sudden changes its velocity and/or direction, we can always find an interaction between that object and its surroundings that is responsible for this change. This equation is one of the most useful in classical physics. Understand that the diagrams and mathematics here could be applied to any type of vector such as a displacement, velocity, or acceleration vector. AP Physics 1 review of Waves and Harmonic motion.
