Question

The contact force and action-at-a-distance force are the same.

• A. True
• B. False

Answer 1

The correct option is B False

1. Force can be classified into two groups: contact force and non-contact force.
2. Contact force is a force that is applied by objects in contact with each other.
3. Frictional force is an example of contact force.
4. A non-contact force is a force applied to an object by another body that is not in direct contact with it.
5. Another name of non-contact force is action-at-a-distance force .
6. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction.
7. The gravitational force is an example of non-contact force.
8. So, the contact force and action-at-a-distance force are the not the same.

Hence, the given statement is false.
