The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question:** The question asks for the name of the force that opposes motion between surfaces that are in contact. 2. **Identifying the Relevant Concept:** In physics, when two surfaces are in contact and one surface attempts to move relative to the other, a specific force acts to resist this motion. 3. **Defining the Force:** This resisting force is known as "friction." Friction acts in the opposite direction of the motion, thereby opposing it. 4. **Explaining the Mechanism:** When one surface moves or tries to move over another, the microscopic irregularities on the surfaces interact, creating a force that opposes the motion. This is true for both static (not moving) and kinetic (moving) friction. 5. **Conclusion:** Therefore, the answer to the question is: "Friction." ---

    Name the force which always oppose motion.

    Which of the following is not true about Frictional force ? A. Friction is the force which opposes the relative motion of two surface in contact B. The force of friction that acts when a body is moving (sliding) on a surface is called sliding friction. C. Friction in machines wastes energy and also causes wear and tear. D. Rolling friction is much more than sliding friction, the use of ball bearing in a machine considerably reduces friction.

    (A) : Force of friction applied by ground on the wheels of a bicycle is always in the direction of motion of the bicycle . (R) : Force of friction always opposes the relative motion between the surfaces in contact .

    Friction between any two surfaces in contact is the force that opposes the relative motion between them The force of limiting friction (F) between any two surfaces in contact is directly proportional to the normal reaction (R) between them F prop R or F = mu R where mu is coefficient of limiting friction If theta is angle of friction then mu = tan theta A force of 49N is just able to move a block of wood weighing 10kg on a rough horizontal surface The coefficient of friction is .
