Objectives 1. Define force and discuss the characteristics of a force. 2. Compose and resolve forces according to vector operations. 3. Discuss Newton's law of gravitation and how it affects human  movement. 4. State Newton's three laws of motion and their relevance to  human movement. 5. Differentiate between a contact and a noncontact force. 6. Discuss the six types of contact forces and how each affects  human movement. 7. Represent the external forces acting on the human body on a  free body diagram.

Objectives 8. Define the impulse-momentum relationship. 9. Define the work-energy relationship. 10. Discuss the concepts of internal and external work. 11. Discuss the forces acting on an object as it moves along a  curved path. 12. Discuss the relationships between force, pressure, work,  energy, and power. 13. Discuss selected research studies that used a linear kinetic  approach.

Linear Kinetics Kinematics is the description of motion. Kinetics deals with the causes of motion. This chapter deals with the causes of translatory motion, hence  linear kinetics. The concept of force is the basis for understanding linear kinetics.

Force  Force is a vector. Force is a push, pull, rub (friction), or blow (impact). Force causes or tends to cause motion (acceleration) or a change  in shape of an object.  Force vectors are usually drawn as  arrows indicating direction and  magnitude.

Law of Motion Law I: Law of Inertia Every body continues in its state of rest or of uniform motion  (constant velocity) in a straight line, unless it is compelled to  change that state by external forces impressed upon it. If Σ F = 0 then v = 0
Image of page 10
The change of motion is proportional to the force impressed and  is made in the direction of the straight line in which that force is  impressed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
