Question
What is meant by a non-contact force, and can you provide two examples?

A non-contact force is a force that can act on an object without physical contact. Examples include gravitational force and magnetic force.
Explanation
This question tests the understanding of the concept of non-contact forces and requires students to identify specific examples, demonstrating their grasp of the topic.
Common mistake
Confusing Contact and Non-Contact Forces
Students often confuse contact forces (like friction) with non-contact forces (like gravity), thinking they behave the same way.
To fix this, remember that contact forces require objects to touch, while non-contact forces can act at a distance through fields.
