Question
Explain how gravitational force acts as a non-contact force and describe its effect on an object.
Answer
Gravitational force acts at a distance, pulling objects towards each other without any physical contact. It causes objects to accelerate towards the center of mass, resulting in weight.
Explanation
This question assesses the ability to explain the nature of gravitational force as a non-contact force and its impact on objects, testing both conceptual understanding and application.
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.
