Q1: In
the diagram above there are three locations denoted by the letters A, B,
and C. Draw separate force diagrams for our particle when placed at each
location. Show the net force acting on the particle. If the
net force equals zero, state this as your answer. Explain your answer.
Q2:
Suppose our particle is moved from point D to point E, with constant velocity
like a bead on a frictionless wire. Explain what work must be done
by (or removed from) our system. Explain your answer.
Q3:
Suppose our particle is moved from point F to point G. How much work
must be done by (or removed from) our system. Explain your answer. |
