According to newton's third law of motion, when a hammer hits a nail, the nail will exert less force on the hammer, more force on the hammer or an equal force on the hammer.
What is an equal force on the hammer?

Forces can only be added together if they are doing this.
What is acting on the same object?

Intentionally adding friction means you want to add friction to something. Would adding sand to a driveway in winter be an example of intentional friction?
What is yes?
