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
Through the course of tennis history, players’ performance enhancement evolved around the strokes and its effective application for the purpose of winning points in the competitive environment. Players’ stroke execution is surely one of the most researched field in the game of tennis as all tennis players, no matter of the level of their game or competitive involvement, are mostly attentive to the stroke mechanics and consistency of their body parts movement in space and time. Players usually try to be mostly aware of their own hitting space, with a tendency to underestimate the fact that tennis is a game of movements and interactions.
In order to keep lateral momentum as a source of power, the player needs to keep the inertia (lateral direction) without pulling the breaks before the stroke transferring the linear momentum into the forward momentum
