Ever wonder how soccer players are able to perform tricks with the balls?

When the soccer player angles his leg by the ball, the energy in the player's foot is transferred into the ball. Energy can never be destroyed. So therefore, it will always be conserved by transferring into other objects.  When juggling, the player kicks the ball towards but gravity will always bring t down. The explanation towards that is because gravity attracts all objects towards each other, gravitational pull is stronger. As a soccer player makes his way down the field, the opponents will try to stop them. A way to stopping the is by tackling/sliding under the  lower body of a person with the ball to stop the movement of the ball. When an object isn't moving it won't move until another force makes it move. When an object is moving it, it won't stop until another force makes it stop.
