Differentiate between the two types For contact forces, the agent and receiver of the
of forces. force must touch; for field forces, no contact is
needed


Give an example of a contact force. Baseball and baseball bat


Give an example of a field force. Gravity, electricity, and magnetism are all field
forces


What are the parts of a free body You draw the object and all of the forces acting on
diagram? the object


Be able to draw a free body diagram
of a book resting on a table.




Be able to draw a free body diagram
of a baseball player sliding into
second base.




Be able to draw a free body diagram
of a rocket during liftoff.
