Question 1
A block weighing 20 N is pulled horizontally on a rough surface with a force of 10 N. Calculate the net force acting on the block and discuss the motion.
💡 Hint: Identify the friction force based on roughness and normal force.
Question 2
What happens to the frictional force when the surface area of contact increases, assuming weight stays the same? Analyze the change in friction.
💡 Hint: Consider how friction is calculated and which factors are important.
