As you strike a match, friction creates
enough heat to ignite a chemical
compound in the match head that then
burns the rest of the match head.
• As you try to step forward, you push your
foot backward. Friction holds your foot to
the ground, allowing you to walk and run.
Think about how difficult it is to walk on
ice or slippery surface, where there is
little friction.
• The same goes for a car’s tires rolling on
the road
