forces+change+motion

force-a force is a push or pull of an object

forces cause objects to move or stop moving. the motion of an object depends on all of the forces acting on it.

lift-created by force+pressure

drag- a force that moves an object forward

thrust- force that moves an object forward

forces in a direction of an object in motion will seep up the object forces in the opposite direction of the movement will show the object down

the faster the shark moves it's tail the more thrust it will have. the faster the shark moves the more drag will be acting against it's forward motion.
