If we didn't have force, nothing would move, not even a truck, not even a ball.  Nothing, no nothing, no nothing at all.

A truck couldn't move without an engine.  The pistons in the engine force the cam shaft to move which moves the drive shaft, which moves the gears in the universal joint, which in turn moves the wheels of the truck.

                                                                    Moving                                                                   

The pistons are connected to the cam shaft.

The cam shaft is connected to the drive shaft.

The drive shaft is connected to the universal joint.

The  universal joint is connected to the wheels.

And that's the way we move!

A ball hits the floor and exerts a force on a floor.  The floor exerts a force on the ball, and the ball bounces.  Cool huh?

A whale breaches, jumps out of the water.  How?  He uses his muscles to pump his fluke three or for times.  The pushing of the fluke forces the whale out of the water.  They can jump as high as 45 feet.
