Challenge Problems
Push your limits with challenges.
Question 1
A student pushes a 12 kg box on a flat surface. If the coefficient of friction is 0.25, how much force is required to start moving the box?
💡 Hint: Calculate the normal force before applying the coefficient.
Question 2
Design an experiment to compare static and kinetic friction coefficients for two different surfaces.
💡 Hint: Make sure to keep the variables controlled.
