Biomechanics Test 1 UTSA Study Guide
Solutions
Biomechanics - ANSWER✔✔-: The study of forces and their effect on living systems
• Kinematics - ANSWER✔✔-Effects of fluid dynamics on linear kinematics "description of motion"
• Kinetics - ANSWER✔✔-Forces/Linear kinetics, Torque/ Angular Kinetics "causes of motion"
• Effects of Force: - ANSWER✔✔-Properties of biological materials, concept of injury & rehabilitation
"effects of forces inside our body"
• Kinematics vs Kinetics - ANSWER✔✔-is the description of motion, linear kinematics
Kinetics vs Kinematics - ANSWER✔✔-Is the causes of motion, forces/linear kinetics
• Application of Biomechanics - ANSWER✔✔-Technique improvement, training improvement,
equipment/facility improvement, change in rules/regulations. Performance enhancement and injury
prevention.
• Linear Motion - ANSWER✔✔-Body travels along parallel paths
• General Motion - ANSWER✔✔-Combination of translation and rotation

• Angular Motion - ANSWER✔✔-All points on an object move in circles on the same fixed axis
• Rectilinear - ANSWER✔✔-Movement in straight line path (frame of a bicycle on flat road)
• Curvilinear - ANSWER✔✔-Movement in straight curved path (head of a distance runner
• Distance - ANSWER✔✔-"Length of path" followed by object from initial to final position (straight think
sprint)
• Displacement - ANSWER✔✔-"Straight line distance" in a specific direction from initial to final position
(curvy think marathon)
• Speed - ANSWER✔✔-A distance traveled over time
• Velocity - ANSWER✔✔-A displacement covered over time
• Acceleration - ANSWER✔✔-Rate of change in velocity, is present when there is a change in magnitude
and/or direction of velocity
• Projectile - ANSWER✔✔-an object that has been projected into the air or dropped and is only acted on
by the forces of gravity and air resistance (soccer ball after impact, diver after take off, ball dropped from
building)
• Acceleration due to gravity - ANSWER✔✔-force of gravity causes change in vertical velocity at a rate of
-9.81m/s2 every second. Speeds up in a downward direction by +9.81m/s2
