Friction:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>When you push a bike, the wheels reduce the friction with the ground, making it easier to move.<\/li>\n\n\n\n<li>A car&#8217;s tires reduce friction, allowing it to move smoothly on roads.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-link-color has-large-font-size
