← Sports & EntertainmentA figure skater increases their lean angle during a glide; which consequence follows regarding contact area?
A)Area increases, pressure decreases rapidly
B)Area and pressure remain constant
C)Area decreases, friction increases rapidly
D)Area increases, friction heat increases✓
💡 Explanation
As the lean angle increases, the skater applies more force to the ice, increasing the contact area due to slight melting. This results in increased friction and heat generation because the increased pressure leads to more frictional force. Therefore, the area increases, and friction generates more heat, rather than decreased pressure or constant conditions.
