What forces are regarded as contact forces?
There are two main groups of forces; contact and non-contact (field) forces. Contact forces act when objects are in contact (touching) with each other. Friction, tension and compression are examples of contact forces. Friction is the force opposing motion between two surfaces as they rub against each other.

Which is contact force?
Contact force is a force that is applied by objects in contact with each other. The 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. Contact force is governed by Newton's Laws.

What are some examples of contact force?
A good example of contact force is a horse pulling a wagon throughout the journey of his master. Another example is the force of friction slowing down a moving vehicle after applying the brakes. A third example is a stretched spring closing the door automatically after somebody passed through the door.
What are contact forces?
Contact forces are forces which are caused by two objects touching each other. There are lots of different elementary forces which physicists study such as Electric and Magnetic (both of these are components of electromagnetic force), gravitational, and nuclear forces. Contact forces are a result of electric force. At large distances from each other the electric force between two electrically neutral objects is extremely weak. However, when they come close enough to each other the electrons on the surface of one object start to interact with those on the surface of the other object which keeps
What is held by gravitational force?
Everything u see near u is held by gravitational force and also u and your mobile in which u reading about gravity apple from tree comes down because of gravitation force, sky diving is possible because of gravity, surfing, boating, bike riding, walking, running, fighting, car racing , even most popular game and my favourite game football ,think when u kick the football it will never come back, cricket, all games, hoarse riding, there will be no fountain.Think water of fountain will go only up ,it will be amazing when water will go up because all water from earth can go up from earth even the
How does force arise from intraction?
Force arises from intraction between two bodies by contact force we means that the force are transmitted between bodies by a shot range atomic or molecular interaction. Best example is push or pull
How to feel the force of a wall?
Stand up, reach out your arm and lean against a convenient wall. Feel that force? The wall is exerting a contact force on your hand and you hand is exerting an equal and opposite contact force against the wall.
What is applied force?
An applied force is any force exerted by object A on object B . There will also be a reactive force of B exerted on A, and these two forces will be equal and opposite. This is true for all forces - they always appear in pairs, which act on different objects or different parts of the same object.
When two objects are brought closer and closer to each other, a point is reached?
When 2 objects are brought closer and closer to each other, a point is reached where the outer electron clouds of each object interact with each other, applying equal and opposite forces on each other. They occur when one billiard ball hits another, for example, or when asteroids collide with each other.
Answer
Pushing a car up a hill" is one of the "example as force is continuously applied by the person on the car
Answer
In physics, a contact force is a force that acts at the point of contact between two objects, in contrast to body forces. One example would be Kicking a Soccer ball. Here force is applied to the ball with a given mass for a given time and we can see the ball is moving away with some velocity in a particular direction.

What is contact force?
Contact forces are forces that act between the objects in close contact with each other. In simpler terms, a contact force acts between the bodies that are physically touching each other. The contact forces act at the point of direct contact between the two surfaces. Newton’s laws of motion govern contact forces. We deal with various types of contact forces, and these are:
What is the force of contact?
The objects placed in physical contact exert forces on one another, and these are contact forces. Based on the types of surfaces that are in contact, we get various types of contact forces. When the force a rope, string, wire or chain exerts a force on an object, such a force is called Tension force. In the pulley’s case, the ropes that pull the blocks exert a tension force on them. Thus tension force is a pull force and can not be used to exert a push. While drawing the free body diagrams of objects under forces, people draw the force of tension in the wrong direction, so here, it is important to remember that tension can only pull on an object.
What is the force that is exerted on an object when placed on a stable surface?
The contact force exerted on an object when placed on a stable surface is called the normal force. This force comes up to support the object that is being placed on a stable object. It is called the ‘normal’ force because it acts perpendicular to the two surfaces in contact. For example, if a book is resting upon a surface, the surface exerts an upward force upon the book to support the book’s weight.
What is friction force?
The friction force arises when there is relative motion between two surfaces. This force is exerted by a surface as an object moves across it or makes an effort to move across it. Friction is everywhere. We will not be able to walk if there were no force of friction. Broadly the force of friction is of two types:
What is muscular force?
Thus, muscular force can be defined as the force exerted by the muscles of our body. Human beings perform various activities like jumping, running, swimming, twisting, laughing, lifting, stretching, squeezing.
How is normal force determined?
The normal force equals the object’s weight if the object is not under acceleration or retardation. When an object is about to fall, the normal force will be determined by the position at which the object falls on the ground.
What is the force of attraction or repulsion arising from the static charges present in the body called?
Electrostatic Force : The force of attraction or repulsion arising from the static charges present in the body is called the electrostatic force . As this force is present without direct contact between the two bodies, this is a non-contact force.
Answer
Contact forces act on the point of contact, so think like a chainsaw and a tree.

- As the name suggests, the forces that act between two bodies that are not in contact with each other are called ‘non-contact’ forces. These forces act between two bodies that are not physically touching each other.
