Explain the effective use of the three components of physical delivery

What will be an ideal response?

The three components are gestures, movement, and posture.
Gestures are hand and arm movements used during speaking. Gestures should be
conversational and natural yet definite. It is important that your gestures be varied, not
overdone, and appropriate for the audience and situation.
Movement (the change of location during a presentation) should be purposeful and
consistent with the verbal portion of your message. Speakers can adapt to the physical
surroundings to get closer to their audience and should also adapt to the cultural
expectations of audience members.
Posture, or the speaker?s stance, is also important because it may reflect on your
credibility. Speakers should avoid slouching, shifts in weight, or drooping their heads.
In an informal presentation, it may be appropriate to perch on the edge of a desk or
stool but not to sit or lean. Your posture should reflect your interest and attention to
your audience and your presentation.
