If the box is slided then, when the box starts sliding, the contact points on its surface do not get enough time to lock into the contact point on the floor. So, the sliding friction is slightly less than the static friction and we find it easier to move the box already in motion than to get it started.<\/p>\n<hr \/>\n<p style=\"text-align: center;\">NCERT Solutions for Class 8 Science Friction<\/p>\n<h6><span class=\"ez-toc-section\" id=\"9_Give_examples_to_show_that_friction_is_both_a_friend_and_foe\"><\/span><strong>9.
