The correct Answer is:
To determine whether the statement "Frictional force always acts in a direction opposite to the weight of the body" is true or false, we can analyze the concepts of weight and frictional force step by step. ### Step 1: Understand the Definition of Weight - Weight is the force exerted on an object due to gravity. It acts downward towards the center of the Earth. - The weight (W) of an object can be calculated using the formula: \[ W = m \times g \] where \( m \) is the mass of the object and \( g \) is the acceleration due to gravity. **Hint:** Remember that weight always acts downwards. ### Step 2: Identify the Direction of Frictional Force - Frictional force acts to oppose the relative motion between two surfaces in contact. - If an object is sliding to the right on a surface, the frictional force will act to the left, opposing that motion. **Hint:** Friction always opposes motion, not necessarily weight. ### Step 3: Analyze the Relationship Between Weight and Normal Force - The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface. - The normal force acts upward, opposing the downward weight of the object. **Hint:** Normal force is opposite to weight, not friction. ### Step 4: Conclusion About the Statement - The statement claims that frictional force acts in a direction opposite to the weight of the body. However, this is incorrect. - Frictional force acts opposite to the direction of motion, while weight acts downward. Therefore, the frictional force does not necessarily oppose the weight. **Final Answer:** The statement is **False**.
