It is an opposing force caused by friction between the liquid or gas and the surface of an object. This is a force that slows the movement of an object due to rough surfaces. This shape helps air to pass over and below an object smoothly. It is something that measures weight which is sometimes called a spring-balance. science is a necessity in this technological world in which we live. While all of these arguments are true, not one of them is the real reason that we should teach our children science. The most important reason to teach science in elementary school is to give your children an understand - ing that God is our Creator, and the Bible can be trusted.

The force of friction always acts in the direction opposite to that of the applied force. Since friction is a type of force, it is measured in Newton (N). Answer : Aeroplanes are streamlined so that air offers minimum friction.
Whenever an object moves against another object, it feels frictional forces. These forces act in the opposite direction to the movement. Friction makes it more difficult for things to move. The answer lies in how each bridge type deals with the important forces of compression and tension. Tension: What happens to a rope during a game of tug-of-war? Correct, it undergoes tension from the two sweaty opposing teams pulling on it. This force also acts on bridge structures, resulting in tensional stress. Science Questions and Answers from Chegg.
