Facts about Force
By Sharon Fabian
  

1     Force is a word that has lots of different meanings and different uses. Just in the field of science, people use the word force when talking about several different topics. For instance, there is electrical force, the force of gravity, and the force of magnetism. Nuclear force holds atoms, and about everything else, together. Nuclear force is one of the many kinds of force used to produce energy. Another kind of force is mechanical force. When you study "force and motion" in science, mechanical force is the kind that you will usually be talking about. The word force means a push or a pull, or to be a little bit more scientific, it means anything that causes the shape or motion of an object to change.
 
2     A football player uses force to run, kick, pass, and tackle. When he kicks the football, the speed and direction of the football change and the shape of the football changes temporarily, too.
 
3     Force is needed to run a football for a touchdown. Force can also stop the runner in his tracks with a surprise tackle. The amount of force depends on the mass of the person or object producing the force. That is why large football players tend to have the advantage. The amount of force produced doesn't only depend on mass however; it also depends on acceleration, or how fast the football player can speed up. That's why being big isn't enough. A good football player has to be able to move, too.
