Hint: Frictional force is the force generated when two surfaces collide and roll against one another. The frictional force is influenced by a number of factors and the amount of force impelling these forces together is mostly influenced by the surface structure and the amount of force impelling them together.
Complete answer:
We know that friction occurs when two surfaces come into contact. Hence it prevents the target from moving because the anomalies on both surfaces lock against each other, preventing it from moving forward. As a result, frictional force resists the applying force at all times.
We should also remember that the purpose of friction is to avoid the motion of the body, so it acts in the opposite direction of the body's motion at any given time. It also only happens while the body is moved or preparing to move. When I say motion, I'm referring to relative motion. The trajectory of frictional force will always be the inverse of the moving body's motion. Hence, force of friction is always opposite the applied force.
Therefore, the correct answer is opposite.
Note:Remember that the frictional force opposes the force applied to an object in static friction, and the object stays at rest until the static friction force is overcome. A force that acts between moving surfaces is referred to as kinetic friction. A body moving on the surface is subjected to a force that opposes its movement. The magnitude of the force can be determined by the kinetic friction coefficient between the two materials.
