Biomechanics and tennis - PubMed Central (PMC)Success in tennis is greatly affected by the technique a player uses and biomechanics plays an integral role in stroke production. All strokes have a fundamental mechanical structure, and sports injuries primarily have a mechanical cause. 1 Player development based on scientific evidence allows an individualised approach to be structured, with due consideration to the key mechanical features ...

Rotation Angle and Angular Velocity | PhysicsFigure 4. A car moving at a velocity v to the right has a tire rotating with an angular velocity ω.The speed of the tread of the tire relative to the axle is v, the same as if the car were jacked up.Thus the car moves forward at linear velocity v = rω, where r is the tire radius. A larger angular velocity for the tire means a greater velocity for the car.

NOTE (3/27/08): This article is a summary of the published literature concerning batted-ball speed and bat WEIGHT. However, a great deal of recent research clearly indicates that the distribution of weight (as measured by the moment-of-inertia) is far more important than the weight itself.
