Forces only exist as a result of an interaction. Drag force. Which one of the following forces is a contact force? In this example, you can observe two types of forces. Contact forces are those forces that cause a change in another object because the objects are physically touching one another, according to Reference.com. 1. Answer: A force is a push or pull upon an object resulting from the object's interaction with another object. Q. Moon orbiting. Which of the following forces is an example of a contact force? Examples of contact forces include applied force, tension force, air resistance force and normal force. There are other forces which are contact forces. electric force can attract and repel c.) electric force is inversely proportional to the square of the distance between objects d.) gravitational force exists between objects that are not touching It can act at a distance without the need of any intervening medium. Friction involves the rubbing of things together to create energy. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion . Question bank for Class 8. In order for force to exist, interaction between two objects must take place. Force acting on per unit area is called. 5 : to achieve or win by strength in struggle or violence: such as. a.) The person is pulling the rope and the block is pulling back on the rope in the opposite direction. When the interaction ceases, the two objects no longer experience the force. which of the following best represents a difference between electric and gravitational force? 3. Tension B. Which of the following is a good example of a contact force? Which of the following is a contact force? Home. 30 seconds. The s um of all forces acting on an object and direction. A force acting in the opposite direction of an object in motion. The contact force is indeed caused by "Contact". The box is displaced to the right as shown. Contact force is governed by Newton’s Laws. A force which can be applied only when it is in contact with an object is called a contact force. Correct answer is option 'D'. A force is considered a contact force when contact between surfaces of objects is needed for it to transpire. Force acting on per unit area is called.
