Question

The tires you choose to drive over icy roads will create more friction with the road than your summer tires. Give another example where more friction is desirable.

a) Sliding on a water slide.

b) Skiing down a slope.

c) Ice skating on a rink.

d) Walking on a slippery surface.

Answer 1

Friction is desirable in situations where stability, control, and traction are needed. For example, skiing down a slope, walking on a slippery surface, and ice skating on a rink.

Step-by-step explanation:

Friction is a force that opposes motion between surfaces in contact. When more friction is desirable, it can help provide stability and control. One example is skiing down a slope - the friction between the skis and the snow allows the skier to slow down and change direction. Another example is walking on a slippery surface - the friction between the shoes and the ground helps prevent slipping and provides traction. Lastly, when ice skating on a rink, the friction between the ice and the skates allows the skater to glide and perform maneuvers.
