Answer 2

Answer:

1. Contact forces: objects are in contact with each other and exert forces on each other. Non-contact (field) forces: objects are not in contact with each other and exert forces on each other.
2. Examples of contact forces:-

• Reaction force. An object at rest on a surface experiences reaction force . ...
• Tension. An object that is being stretched experiences a tension force. ...
• Friction. Two objects sliding past each other experience friction forces. ...
• Air resistance.

3. Examples of field forces :-

• An apple falling down from a tree is one of the best examples of non-contact force.
• Iron pins attracted in the presence of a magnet bar without any physical contact.
• Falling of raindrops on earth is also an example of non-contact force.
