No. A couple of examples:-

. The Cosmic Microwave background, is the residual radiation signature left over from the time of the creation of the Universe from the Big Bang.

. The determination, by means of a spectroscope, of the spectral lines indicating the presence of particular elements in a distant star.

. You may argue that the traffic microwave radar has its waves impinging on the target vehicle, but most would consider this a non-contact measurement.

Which force exists between objects in the absence of direct physical contact?

Gravitational force exists between objects in the absence of direct physical contact. This force is a result of mass and distance between objects, attracting them towards each other.


What is a force that results from physical contact between two objects called?

The force that results from physical contact between two objects is called contact force. This force can include friction, tension, normal force, and applied force.


What is the difference between contact force and field force?

Contact force acts through direct physical contact between objects, such as friction or normal force, while field force acts at a distance without direct contact, such as gravitational or electrical forces. Contact forces require objects to be in physical contact, while field forces can act between objects even if they are not touching.


What is a contact force magnetic force gravity or air resistance or electrical force?

Gravity is a non-contact force that acts at a distance between two objects with mass. Contact forces, such as friction and normal force, require physical contact between objects. Magnetic force, electrical force, and air resistance also act without physical contact between objects.


could conduction happen between two objects that were not touching?

No, conduction requires physical contact between objects to transfer heat. Without direct contact, conduction cannot occur.


What is the difference between contact and non-contact force -?

contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover


Is tearing a contact or non contact force?

Tearing is a contact force because it involves physical interaction between two objects, such as pulling a material apart with physical force.


Is gravity a contact or non contack force?

Gravity is a non-contact force, meaning it can exert its influence on objects without direct physical contact between them. This force is responsible for the attraction between all objects with mass.


Is thrust contact or non-contact force?

Thrust is a contact force, as it involves physical contact between objects or surfaces that are interacting to create the force.


What are the two categories of forces?

The two categories of forces are contact forces, which occur when two objects are physically touching, and non-contact forces, which act between objects that are not in direct physical contact.


How does energy transfer between objects that are not in physical contact with each other?

Energy can transfer between objects that are not in physical contact through electromagnetic radiation, such as light or heat. This transfer occurs through waves or particles that carry the energy from one object to another.


How will you differentiate contact from non-contact?

Contact forces involve direct physical interaction between objects, such as friction or tension, while non-contact forces act at a distance, such as gravity or magnetic force. Contact forces are mediators introducing reaction force and normal forces, whereas non-contact forces involve no physical touch between objects.
