What is the direction of the force of friction in relation to the direction of motion?
Understand the Problem
The question is asking about the relationship between the force of friction and the direction of motion, specifically which option correctly describes how the friction force behaves in relation to motion.
Answer
Opposite to the direction of motion.
The force of friction always acts in the opposite direction to the motion of the object or to the force trying to move it.
Answer for screen readers
The force of friction always acts in the opposite direction to the motion of the object or to the force trying to move it.
More Information
Frictional force opposes relative motion between two surfaces. It ensures gripping and prevents slipping in many applications such as tires on roads.
Tips
A common mistake is thinking friction always acts to stop an object. It only opposes motion relative to the contact surface.
