. Sketch a graph of the magnitude of the kinetic frictional force on a sliding block as a function of the magnitude of the normal force. 2. Does the kinetic frictional force on the block increase, decrease, or stay the same as the normal force on the block increases? Is the relationship linear, or curved? Explain your reasoning.
