Force concentration

Force concentration is the concept of focusing all your energy in one spot to make it more powerful. Imagine you have a pile of sand and you want to pick up as much sand as possible with one hand. You wouldn’t just grab a handful of sand loosely, because it would slip out of your hand. Instead, you would make a fist and grab onto the sand tightly in one spot. That’s because the force of your hand is concentrated in one area and makes it easier to pick up the sand.

Similarly, in sports, athletes use force concentration to hit harder, jump higher or throw farther. For example, in baseball, the pitcher wants the ball to go as fast as possible, so they concentrate their force in their pitching arm and use their whole body to send the ball flying.

In engineering, force concentration is also important. If you want to lift something heavy, you would use a crane, which concentrates the force in one area, making it easier to lift the heavy object.

Overall, force concentration is the act of focusing all your energy in one spot to make it more powerful, whether you’re picking up sand, throwing a ball, or lifting something heavy.
