Your free body diagram is correct the object isnt at constant velocity though because it is being. The force of gravity is decreasing the momentum of the ball momentum is mass times velocity. Free body diagramshelp plz.

The direction of the arrow shows the direction that the force is acting. It is generally customary in a free body diagram to represent the object by a box and to draw the force arrow from the center of the box outward in the direction. As soon as you let go of the ball at no point is it speeding up.

A ball on a string moves in a vertical circle as shown. Physical problems for example calculating the force on the bungee jumper by the bungee cord are much easier to solve once youve drawn a complete and correct free body diagram. For the marble at the left side of the cone the free body diagram is correct.

This video is part of the representations video series. Each force arrow in the diagram is labeled to indicate the exact type of force. Explain fully using a free body diagram and accompanying equations.
