Explain giving two examples each of :
(a) Contact forces, and (b) Non-o contact forces.
Explain giving two examples each of :
(a) Contact forces, and (b) Non-o contact forces.
The non-contact force acts on the physically separated objects; for example, gravitational force or the force between the sun and stars, electric force, magnetic force. The contact force acts on the interacting objects which are physically connected with each other; for example, normal force, friction, applied force, air resistance, tension etc. let’s discuss all about the contact force and its complete explanation. A force is that Physical cause which changes (or tends to change) either the size or the shape or the state of rest or of motion of the body.
We are Familiar that a force when applied on a body can produce two main effects,
1) It can change the state of rest i.e., it can Produce motion in the body.
2) It can change the size or shape of the body i.e., it can change the dimension of the body.
A Contact force as the name suggests acts on a point of an object by direct contact. Forces that act between the objects are in contact with each other are called Contact Forces. These forces are produced and experienced when a body comes in contact with another body. The Contact may be Continuous or sometimes momentary. The former case is known as Continuous force and the latter case is known as impulse force.
contact forces are mainly of following types
muscular force and frictional force
non contact forces are as follows
magnetic force
gravitational force.
electrostatic force
