мє τσ τнє вαℓσr cℓυв___✳ Define/Explain the following.1. Force2. CONTACT forces3. Non-contact forces4. FLUID friction_______________________________=> To define the following :-Force :- Push or pull of an object is CONSIDERED a force. Push and pull come from the objects interacting with one another. In SI base units: kg·m/s2.F = m a____________________________Contact FORCES :- Contact force is a force that is applied by objects in contact with each other. Contact force acts on a point of DIRECT contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. It is of three types :-Frictional ForceApplied ForceNormal Force______________________________Non-contact forces :- A non-contact force is a force applied on an object by another body without being in direct contact with the object.Examples:-Gravitational forceGravitational forceElectromagnetic forceGravitational forceElectromagnetic forceStrong Nuclear forceGravitational forceElectromagnetic forceStrong Nuclear forceWeak Nuclear force_______________________________ Fluid friction :- Fluid friction is the resistance to an object's motion through a liquid or gas. When the motion is occurring in a liquid, it is referred to as viscous resistance. As an example, when an object falls through water, its speed reduces due to fluid friction acting on it.____________________________________Hope it help you ☺
