Biomechanics Quiz

Define the term biomechanics.

• The study of mechanical laws relating to the movement or structure of living organisms.

• The study of chemical processes within and relating to living organisms.

• The study of the physical structure of organisms.

• The study of the interaction between organisms and their environment.

Which of the following defines speed, velocity, acceleration, and deceleration?

• Speed is the rate of change of distance, velocity is speed with direction, acceleration is the rate of change of velocity, and deceleration is negative acceleration.

• Speed is the rate of change of velocity, velocity is speed without direction, acceleration is the rate of change of distance, and deceleration is positive acceleration.

• Speed is the rate of change of distance, velocity is speed without direction, acceleration is the rate of change of speed, and deceleration is positive acceleration.

• Speed is the rate of change of velocity, velocity is speed with direction, acceleration is the rate of change of distance, and deceleration is negative acceleration.
