7-3 Free-body Diagrams for Circular Motion, Part 1
For each situation 1- 10, follow the steps below to write the equation for Fc
• Identify the object, its circular path, and the center of the circle.
Draw the free-body diagram (FBD).
DO include all forces that act on the object.
DO NOT include forces the object exerts on its surroundings.
Sketch the radial (±r) and the tangential (±t) or perpendicular (±p) axes on the FBD.
The radial axis, r, points from the object to the center of the circle.
Radially inward is the +r direction. Radially outward is the -r direction.
Write an equation for Fc in terms of the forces acting on the object. For example,
Fc= Fg - FN.
