Question
Which of the following is an example of a contact force?Select one:a.gravityb.magnetic forcec.frictiond.electric force
Solution
The correct answer is c. Friction. This is because contact forces are those types of forces that result when the two interacting objects are perceived to be physically contacting each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces. So, friction is a force that always exists between any two surfaces in contact with
