4. External force that attracts a physical body with a mass to the center of the earth.
5. Resistance to the movement of an object through a fluid (such as air or water).
8. Resistance to movement that occurs as a result of the shape of an object.
9. Type of lever where the applied force and the resistance are on the same side of the axis and the applied force is closer to the axis.
10. The study that describes spatial and timing characteristics of motion.
11. The ability to achieve and maintain body stability while remaining still or moving; the process whereby the body’s state of equilibrium is controlled for a given purpose.
13. The application of mechanics to biology in order to understand the physics underlying various forms of movement.
14. Any airborne object.
15. Resistance to movement that occurs as a result of the surface of an object.
17. The measure of how much matter an object has.
19. The study that focuses on the various forces that cause a movement (i.e., the forces that produce the movement and the resulting motion).

1. A relative measure of the ease or difficulty with which equilibrium can be disturbed.
2. Shape of a path followed by the center of mass of a projectile whenever gravity is the only external force acting on the object.
3. The whole mechanism involving Magnus force.
6. A simple dot used to represent the center of mass of a body or object.
7. Study concerned with the generation of rotation about an axis of rotation and the control of these rotations.
9. Flow with visible disturbances that is produced by large, rough bodies and occurs within the boundary layer.
12. Any action, a push or pull, that tends to cause an object to change its state of motion by experiencing acceleration.
16. The technique of taking advantage of the region of air shielded by another athlete’s body
18. Property of objects where because of their mass, they are reluctant to change their state of motion.
