1: Isolate the object. 2: Identify all forces acting on the object. 3: Represent forces as arrows (length = magnitude, direction = force direction). 4: Use a coordinate system.

What are the steps to create a free-body diagram?
1: Isolate the object. 2: Identify all forces acting *on* the object. 3: Represent forces as arrows (length = magnitude, direction = force direction). 4: Use a coordinate system.
What is the GUESS method?
Given, Unknown, Equation, Substitute, Solve.
What is a force?
An interaction between objects that can cause a change in motion.
What is a vector quantity?
A quantity with both magnitude and direction.
What is Newton's Third Law?
For every action, there is an equal and opposite reaction.
What is an inertial reference frame?
A frame in which an object at rest stays at rest, and an object in motion stays in motion with constant velocity unless acted upon by a force.
Define electromagnetic force.
A fundamental force arising from the interaction of electrically charged particles.
What is the unit of force?
Newtons (N).
In a free-body diagram, what does the length of the arrow represent?
The magnitude of the force.
In a free-body diagram, what does the arrowhead indicate?
