Friction

Question 2 • Mad 2017 Phy Sci B -33 SS

Myron was trying to light a match. The first time he struck the match, the match did not light. The second time he tried, the match lit successfully.

Answer
A
Myron increased the friction by decreasing the surface area.
B
Myron increased the friction by increasing speed.
C
Myron decreased the friction by making the match aerodynamic.
D
Myron decreased the friction by lubricating the match.

Explanation

Striking a match creates friction, and that friction produces heat that can ignite the match head. A faster strike can create more heat in a short time, so the best choice is “Myron increased the friction by increasing speed.” Lubricating the match or making it aerodynamic would reduce friction, not help it light.
