Chini is sliding blocks of different materials down a steel ramp. All of the blocks have similar sizes and masses. The table shows the coefficient of friction
for several materials when sliding on steel. The larger the coefficient of friction, the greater the force of friction. In which order would the blocks reach the
bottom of the ramp?
Material
Coefficient
of friction
aluminum
chromium
glass
0.25
0.21
0.12
steel
0.23
titanium
vanadium alloy
0.31
Drag the materials into the correct order from the material that will slide down the ramp the fastest to the material that will slide down the ramp the
slowest
chromium
glass
aluminum
titanium vanadium alloy
steel
