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 the definitions and characteristics of both types of forces.
Answer
Contact forces require touch; field forces act at a distance.
Contact forces require physical contact between objects, such as friction or tension. Field forces act over a distance without contact, like gravity and electromagnetism.
Answer for screen readers
Contact forces require physical contact between objects, such as friction or tension. Field forces act over a distance without contact, like gravity and electromagnetism.
More Information
Field forces can act over long distances, which is why they are crucial in astronomy where celestial bodies interact without touching.
Tips
Confusing the need for contact can lead to misunderstandings; remember, contact forces need touch while field forces don't.
