Do you agree or disagree with the statement "The centripetal force does not belong on a free-body diagram as one of the forces acting on an object"
- yes, because centripetal force is like ma, and should not be on the free-body
diagram. there is no centripetal force, but rather a force of tension, gravity,
friction, or a normal force
- disagree...because the centripetal force affects the objects and must be added to
the free-body diagram
- YES. Centripetal force should appear on a free body diagram. All forces should
be drawn in a free body diagram.
- I disagree, i believe that centripetal force, is a pull directed inward along the
radial axis extending through the object, and should be represented on a free
body diagram
- I do not agree with this statement. The centripetal force is pulling the ball away
from the center of the circle.
- The centripetal force will and should appear on a free-body diagram if there is
circular motion present. Of course it should not be called the centripetal force.
It should be reffered to as what it truely is and that depends on the situation. It
could be the tension on a string or the force due to gravity affecting an orbiting
body.
- I agree, because adding a centripetal force vector to a free body diagram may
seem confusing because it looks like another added force. There is a force
attributed to friction, gravity or some other external force that accounts for this
centripetal force. Having both on a diagram may lead someone to think there
are two forces, when they are one and the same.
