Question

12a. In this experiment, we will be using a force sensor. The force sensor hook mount should be completely tightened before taking measurements. Group of answer choices True False

b. If the simplified friction model, LaTeX: f_k=\mu_k N f k = μ k N , is true, when the normal force on an object is doubled, the kinetic friction force is also doubled. Group of answer choices True False

c. Kinetic friction always points in the direction of the objects motion.True False

d. In general, frictional forces will always oppose motion.True False
