Which Of The Following Is A Contact Force
Pushing a car or kicking a ball are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied to the car by a person, while in the second case the force is delivered in a short impulse.
Which of the following are contract force?
Contact forces are those types of forces which 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.

Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.
What are examples of contact types?
| Contact Force | |
|---|---|
| How are they formed | Between two objects that are in physical contact |
| Field force | Does not exist |
| Types | Friction, tension, normal force, air resistance, and spring force |
| Example | The resistance offered by a floor when a box slides on it |
What are the two contact forces?
a) Name two contact forces. Answer: a) Frictional and applied forces.
Is friction a contact force?
Friction is a contact force when two surfaces interact. The second equation is the kinetic frictional force that is used when two surfaces are sliding against each other.
