Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin.In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called 'animal starch'.hen all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more than one type of monosaccharide is present they are called heteropolysaccharides or heteroglycans.
When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.[1] The force applied on a surface in a direction perpendicular or normal to the surface is called thrust.
A plane's ability to get off the ground depends on four main forces and how they interact with each other. These four forces are thrust, drag, lift, and weight. Thrust is the force created by the plane's engine that pushes it forward. It is similar to the force of a car's engine pushing the car down the road. Drag is the force of the wind pushing back on the plane. Airplanes must contend with the force of drag whether or not it is a windy day because, even on a still day, the effect of air movement is created as the plane flies through the air. Drag pushes the plane in the opposite direction from the direction of thrust.
