Which of the following are the examples of ‘Contact Forces’.
Code:
The correct option is C Only 3, 4 and 5
Contact force is the force in which an object comes in contact with another object. Contact forces are also direct forces. Contact forces is something that pull on it. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. The most common instances of this include friction, normal force, and tension. Contact forces arise also when solids are in contact with fluids. For example, for a solid immersed in a fluid, there is an upward bouyant force equal to the weight of the fluid displaced. The viscous force, air resistance, etc are also examples of contact forces.
A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most familiar example of a non-contact force is weight. All four known fundamental interactions are non-contact forces.
