What is Direct and Indirect force?
Contact forces and non-contact forces are also referred as direct and indirect forces respectively.
Refer to the following link for direct force:
Refer to the following link for indirect force:
Force can be a push or a pull. There are many different kinds of forces that we see everyday. For example, when you open the refrigerator door, you are using a force by pulling on the handle. When the wind blows, it is a strong force that can pull back on our clothing, or push our hair into our face. Some forces are small, and others are very big. Scientists that study forces are called Physicists. Physics is all about what things are made of, and how they move.
Forces can be indirect or direct. When a force is direct, one object touches another, or makes contact. You opening the refrigerator door is a direct force. Indirect force is like a magnet - it pulls on an object (like another magnet, or a paperclip or nail), even though it isn't touching that object. When you are riding a bike downhill, you might notice that you don't have to pedal as much. That is because an indirect force is pulling down on you and the bike. This force is called gravity. Gravity is a force that is always pulling. When you put a cup of water down on the table, it stays there because of gravity. When you jump on a trampoline, you come back down because of gravity. Gravity is such a big force that it controls the way our planet Earth moves around in an orbit, being tugged at by the sun.
