Which two subdisciplines are described as important in the field of biomechanics?
- Physics and chemistry
- Anatomy and physiology
- Kinematics and kinetics
- Motor learning and control
Reveal answer
Answer: Kinematics and kinetics
Source evidence
PDF page 64: Two important subdisciplines in the field of biomechanics are kinematics and kinetics. Kinematics is the branch of classical mechanics that describes the motion of points, objects, and systems of groups of objects, without reference to the causes of motion (i.e., forces).” Instead of studying the forces acting on objects, kinematics focuses on variables such as acceleration,
-
What does kinematics describe?
- The motion of points and objects
- The forces causing motion
- The energy used by cells
- The chemical reactions in muscle
Reveal answer

Kinematics focuses on motion WITHOUT reference to what?
- Trajectories
- Time and position
- The causes of motion (forces)
- Velocity and acceleration
Reveal answer
Answer: The causes of motion (forces)

Kinetics is the study of motion and its causes, particularly what?
- Time
- Forces
- Position
- Displacement
Reveal answer
Answer: Forces
Source evidence
PDF page 64: Kinetics is the study of motion and its causes, particularly forces, and is focused on the explanation of motions (the forces that cause or tend to cause changes in motion). While both kinematics and kinetics describe motion, the key distinguishing feature is that kinetics is
-
What is the key distinguishing feature of kinetics from kinematics?
- Kinetics studies chemistry
- Kinetics ignores motion
- Kinetics measures only time
- Kinetics is concerned with forces
Reveal answer
Answer: Kinetics is concerned with forces
Source evidence
PDF page 64: concerned with forces, whereas kinematics simply describes motion.

-
Kinematics simply does what, according to the text?
- Measures energy
- Describes motion
- Causes changes in motion
- Explains forces
Reveal answer
Answer: Describes motion

-
Kinematic analysis is often used to study the motion of what?
- Cellular respiration
- Chemical forces
- Only external objects
- The body, limbs, and joints
Reveal answer
Answer: The body, limbs, and joints
Source evidence
PDF page 64: Kinematic analysis is often used to study the motion of the body, limbs, and joints that occurs during various human movements, as well as the motion of external objects associated with
-
How many kinematic variables are used in kinematic analysis?
- Five
- Two
- Three
- Four
Reveal answer
Answer: Five
Source evidence
PDF page 64: human motion. There are five kinematic variables used when completing kinematic analysis: Time, position, displacement, velocity, and acceleration. Any or all of these five variables can be used in the analysis and description of movement.
-
Which is one of the five kinematic variables?
- Mass
- Acceleration
- Energy
- Temperature
Reveal answer
Answer: Acceleration

-
Which two variables are described as the most basic kinematic variables?
- Velocity and acceleration
- Displacement and force
- Time and velocity
- Time and position
Reveal answer
Answer: Time and position
Source evidence
PDF page 64: Time and position are the most basic variables, which means they do not depend on the other three variables and can be measured independently. Displacement, velocity, and acceleration
-
Why are time and position considered basic variables?
- They require acceleration
- They can be measured independently
- They depend on velocity
- They are built on displacement
Reveal answer
Answer: They can be measured independently

-
The study of kinetics examines what causes motion, also known as what?
- Velocity
- Force
- Displacement
- Time
Reveal answer
Answer: Force
Source evidence
PDF page 64: The study of kinetics is the study of motion, specifically examining what causes motion, also known as force. Force is described as all motion in the world; we are usually unaware of important forces in the body, for example pushing the pedals on a bike, using a paddle when you row or canoe, or the force that is used when using a racket in various sports.
