Momentum measures the ‘motion content’ of an object and is based on the product of an object’s mass and velocity. For players to perform accurate strokes with high velocity, there should be an optimal combination of linear and angular momentum. The optimal combination depends on the urgency of movement, level of balance, perception of the situation and even level of confidence. With a creation of a larger momentum, greater forces and abilities are required from a hitter to decelerate to set up and execute a successful stroke

Attention in tennis.Transition from external to internal focus of attention
Creating the mental projections of future movement, before the physical response is initiated, is always dependable on the dynamic changes of the environment to which we have to be attentive constantly in order to adapt efficiently
PRINCIPLES OF THE EFFICIENT MOVEMENT and PERFORMANCE
For a player to move the body segments efficiently, there should be optimal combination of the stability and mobility through lowering the center of gravity created by loading the major muscle groups of the lower extremities.
Upper body force creation depends of the elastic capabilities of the muscles of the trunk. The reason the players create a larger upper trunk rotation beyond the hips is to pre stretch the trunk rotator muscles and create a powerful separation angle
