Module 3: Dynamics

• Acceleration: The rate at which an object's velocity changes
• Dynamics: Concerned with the study of forces (linear) and torques (rotational) and their effect on motion.
• Linear motion: Straight line motion when an object moves from one place to another.
• Velocity: The rate at which an object changes its position
• Kinematics: The geometry of motion in terms of two elementary concepts, position and time. Kinematics considers the motion of a body quite apart from the forces either causing the motion or which may be produced as a result of motion.
• Kinetics: Relates to motion to the forces that cause movement or result from movement.
• Rectilinear: Motion in a straight line
• Curvilinear: Motion in a curved path
• Rotary: Curvilinear motion about a fixed axis
• Oscillatory: Repeated motion in which an object repeats the same movement over and over.
• Reciprocal motion: Motion that is moving backwards and forwards in straight line.
