 The combination of forces produced by different parts of the human body. When a person is moving or attempting to move an object, several different parts of the body act together to maximize the force. In theory, force summation occurs when all body parts act simultaneously In practice, the strongest and lowest body parts around the centre of gravity (e.g. trunk and thighs) move first, followed by the weaker, lighter, and faster extremities. This is known as sequential acceleration and results in successive force summation. To obtain a maximum force, summation also needs sequential stabilization of body parts, with some body parts having to be fixed at stable points while other parts produce the effective forces.

Question 2
In order to generate maximum force in a baseball pitch, individuals must use force summation for a successful pitch. Firstly muscles must move in the correct order from largest muscles first to smaller muscles last. Applying a proper, rhythmic sequence is crucial so the force may be transferred from muscle to muscle. 
The first movements in a baseball pitch is the stride, a large step forward which activates the largest muscles including the Gastrocnemius, Hamstrings and Quadriceps. This generates force and momentum which is then transferred to the lower back as the hips rotate in the cocking phase. Continuing the Tricep extensor muscles are used for extreme arm extension as the arm accelerates forward. Lastly, the momentum is transferred to your wrist and fingers, and all of the force generated is finally released through the smallest muscles in the follow through.

Question 3
When a player uses just a few body parts, the force produced will be less than when a player uses many body parts. This is why the best techniques for throwing, kicking and striking use more than just the obvious body part that finishes the action. Also important for force production is the sentences in which parts of the body are used. For best results, movement begins with the larger, slower body parts and finishes with the smaller, faster body parts.

Question 4
one factor is correct sequencing , another factor is balance and base of support

Question 5
F=ma
force=mass x acceleration

That's how the concept of force is defined. If you apply larger amounts of net force on an object, you'll find that the acceleration increases linearly and the property that decides how quickly the acceleration increases is the mass.
