Is drag force a contact or noncontact force?

Is drag force a contact or noncontact force?

It is a type of friction and sometimes called drag. Contact force – is a force that needs to touch an object before it can affect it (e.g. friction). Contact forces need to touch the thing that they are affecting. Examples of contact forces are: Friction, Air resistance, Water resistance and Upthrust.

Which forces are non-contact forces?

Answer. The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.

Which forces are contact forces?

Examples of contact forces include:

• Reaction force. An object at rest on a surface experiences reaction force .
• Tension. An object that is being stretched experiences a tension force.
• Friction. Two objects sliding past each other experience friction forces.
• Air resistance.

Which is not a non-contact force?

Therefore, clearly from the above discussion we can see that magnetic force, electrostatic force and gravitational force are all three non-contact forces. The only left force is muscular force. This means that muscular force is not a non-contact force.

What are three examples of noncontact forces?

Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.

Why is gravity a noncontact force?

Gravitational force is a force of attraction between the earth and the objects on Earth. Gravitational force is considered to be a non-contact force because it is an attracting force which does not include contact between the objects to exert force.

Which of the following is not an example of contact force?

Gravitational force is a non- contact force. The force that always resists one body’s motion above another body is identified as a frictional force. It operates between the two surfaces, which are in connection with each other.

What are some examples of contact and noncontact forces?

Contact may be continuous or impulsive. In acts when there is no physical contact in objects. Muscular force,frictional force,spring force,normal force,tension force are few examples. Gravitational force,electrostatic force,magnetic force and electrochemical force are few examples.

What is contact and noncontact forces Class 8?

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. A non-contact force is a force applied to an object by another body that is not in direct contact with it.

Which of the following is an example of noncontact force?
