of the tennis player depends largely on the mechanics of their forehand swing. The force of impact is determined by the racket speed at the moment it comes in contact with the ball. When maximum distance is used for accelerating that is when maximum velocity can be obtained. Body weight support is necessary for the forehand drive because shifting weight when striking the ball will increase ground reaction force to the body and the ball. A player wants to be balanced to direct power and energy

measure how far it ‘flies’. Doing this will tell me the relationship between force‚ potential energy and kinetic energy. My Prediction: I predict that the further I pull the band back the further it will ‘fly’. This is based on the fact that the more tension involved means that the potential energy is greater therefore the kinetic/moving energy will also be greater. Variables: Force to pull the band back. This will be between 3 and 11 Newton’s. Equations:

people are forced to undertake a difficult change in their lives. This is evident in the feature article Paul de Gelder composed by Caitlin Chang where various language and visual techniques have been combined to portray how events can effect and force upon change in an individual’s life. Throughout the article‚ first person point of view “I” has been used and repeated to assist readers in understanding de Gelder’s life and issues he has had to face along the way.

brutal tendencies‚ often towards traitors within their own ranks. So this kind of brutality was true of both the Bolsheviks and their opposition‚ which means that it was not really an advantage for the Bolsheviks‚ just another tactic employed by all forces; hence it was not a significant reason for the Bolsheviks remaining in power. A temporary policy of the Bolsheviks that incorporated many

A projectile is an object upon which the only force acting is gravity. Many projectiles not only undergo a vertical motion‚ but also undergo a horizontal motion. That is‚ as they move upward or downward they are also moving horizontally. There are the two components of the projectile’s motion - horizontal and vertical motion. And since perpendicular components of motion are independent of each other‚ these two components of motion can be discussed separately. The goal of this part of the lesson is

to Newton’s first law of motion‚ an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural way for objects to keep on doing what they’re doing or keep going the same direction. All objects resist changes in their state of motion. In the absence of an unbalanced force‚ an object in motion will maintain its state of motion. This is often called the law of inertia. The law of inertia is most commonly experienced when

Muscular Strength Muscular strength is the ability of a muscle or group of muscles to exert a force against a resistance in a single contraction. Strength is fundamental for all sports 3. Muscular Endurance Muscular endurance is the ability of a muscle to exert a force repeatedly over an extended period of time. 4.
