Transcription: The study of dynamics is part of a wide field of study called mechanics, which investigates physical forces. Dynamics is concerned with the forces that cause objects to move. There are many different kinds of such forces, for example gravity and friction, which produce many different kinds of motion. The type of motion produced will depend on the size, direction, and duration of the forces that cause it to happen.
