friction acts only when two surfaces move over each other (true or false)​

Answer 1

Answer:

True

Please mark it brainliest

Answer 2

Answer:

This is false(Due to the word only)

Explanation:

Friction is the force opposing the movement of other object. Friction acts when 2 surfaces come in contact with each other by any means i.e. it is a contact force. If there is no contact between 2 forces, friction will not come in play. friction acts in the direction opposite to that of the movement of object
