contact and non contact forces

What is a contact force?

• A contact force is a force that acts at a distance between two objects.

• A contact force is a force that is only present in a vacuum.

• A contact force is a force that is not affected by the materials of the objects in contact.

• A contact force is a force that acts at the point of contact between two objects.

Give an example of a non-contact force.

• Frictional force

• Magnetic force

• Gravitational force

• Electrical force

Explain the difference between contact and non-contact forces.

• Contact forces require physical contact, while non-contact forces can act at a distance.

• Non-contact forces require physical contact.

• Contact forces are stronger than non-contact forces.

• Contact forces can act at a distance, while non-contact forces require direct contact.

How do contact forces affect objects?

• Contact forces only affect objects made of specific materials

• Contact forces always result in objects breaking

• Contact forces have no impact on objects

• Contact forces can cause objects to move, change direction, or deform depending on the magnitude and direction of the force applied.
