KIN 151: BIOMECHANICS I
Here is an overview of some of the material that will be covered on the midterm.
Chapters 1,2: An Introduction to Biomechanics
• Kinesiology is the study of movement
• Biomechanics, a branch of physics, applies the principles of mechanics to living organisms
• Biomechanics can be used to solve informal and formal problems, qualitative and quantitative problems
• Can you define the following terms: Linear motion (translation, rectilinear, and curvilinear), Angular
motion (yaw, pitch, and roll)?
• What are the three cardinal planes that divide up the body and the corresponding axis of rotation?
• Are you familiar with your movement terminology and directions?
Chapter 10: Linear Kinematic Concepts
• Define and apply the terms distance, displacement, speed, velocity, acceleration, projectile, trajectory,
apex, range, instantaneous, average.
• What factors influence projectile motion?
• What factors influence the projectile’s trajectory?
• What are the different types of projectile problems?
• Be able to use the equations used for the laws of motion for constant acceleration.
• Be able to solve any of the problem types from class (or covered in your text) making use of all
formulas and equations presented.
Chapter 11: Angular Kinematic Concepts
• Define and apply the terms relative angle, absolute angle, instant centre, angular distance, angular
displacement, radians, angular speed, angular velocity, angular acceleration, radius of rotation,
tangential acceleration, radial acceleration, total acceleration
• Be able to apply the 3 conversion factors among revolutions, degrees, and radians.
• How do we measure joint angles?
• Why is it important to study angular kinematics?
• What two conditions must be met to convert between linear and angular kinematics?
• Be able to solve any of the problem types discussed in class, on homework assignments or in your
textbook making use of all formulas and equations presented.
Chapter 3: Kinetic Concepts for Analyzing Human Motion
• Define and apply the terms weight, inertia, force, gravity, external vs. internal forces, net force
• Be able to draw and label a free body diagram.
• The effects of a force will depend on what 3 factors?
• Be able to perform vector composition and vector resolution using trigonometry.
• Be able to solve any of the problem types from the Introductory Problems, Additional Problems,
Problem Solving handouts making use of all formulas, geometry applications, and trig functions
we have used.
