Consider a ball rolling around in a circular path on the inner surface of a cone.
path on the inner surface of a cone. The
weight of the ball is shown by the vector W.
Without friction, only one other force acts on
the ball – a normal force.
Draw the normal vector; what relationship
do the vectors have?
A. The normal force is greater than the
weight and less than the centripetal force.
B. The normal force is greater than the
weight and greater than the centripetal
force.
C. The normal force is less than the weight
and greater than the centripetal force.
D. The normal force is less than the weight
and less than the centripetal force

When the 1 kg ball starts to rotate around the horizontal circular path A with a Constant speed of 1 m/s the rope connecting the ball passes through a pulley (in point C, not shown in the figure), which is fixed to the ceiling. A force F is applied as shown in the figure. If the force F on the cord increases, the ball rises and eventually reaches a new position and rotates around the horizontal circular path B. The...

Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...
