Force is an external push or pull on an object that causes it to change speed, direction, or shape.
But how is force created? Force is produced by the transfer of energy from one object to another. When a force is applied to an object, energy is transferred to that object, which results in a change to its state.
Force is the transfer of energy to an object which causes it to change speed, direction, or shape.
For example, when a baseball player swings his bat and hits a baseball, the kinetic energy from the bat is transferred to the ball which pushes it through the air. In other words, the player applies a force on the baseball, which causes it to change direction and speed, by transferring kinetic energy to it with the swing of his bat.
