Explain how contact forces are different from field forces.
Understand the Problem
The question is asking for an explanation of the differences between contact forces and field forces in physics. This requires understanding both concepts and how they interact with objects.
Answer
Contact forces require contact; field forces act at a distance.
Contact forces require physical interaction between objects, like friction or tension, while field forces act over a distance without direct contact, such as gravity or electromagnetism.
Answer for screen readers
Contact forces require physical interaction between objects, like friction or tension, while field forces act over a distance without direct contact, such as gravity or electromagnetism.
More Information
Contact forces involve physical touch, like pushing or pulling, while field forces can exert their influence across space without direct contact.
Tips
A common mistake is confusing the requirement of physical contact for field forces, which is not the case.
