A Force is the act of pushing or pulling an object Force has many forms It can be shown as pressure friction gravity spring and air resistance When you are running the main types of forces that you deal with are friction and air resistance Two other forces that can be seen in running are spring force and gravitational force Forces like friction and air resistance can have a positive and a negative effect on your running The forces acting on a swimming fish are weight buoyancy and hydrodynamic lift in the vertical direction along with thrust and resistance in the horizontal direction Thrust is the force acting in animals direction Lift is the force acting opposite in right angles to the thrust Drag is the force acting in the opposite to the direction of movement Drag is minimized by the streamlined shape of the fish To swim efficiently in water fishes have to overcome the drag maintain their vertical position in the water column and maintain an upright position They should See Answer
