Reduced velocity lag error.<\/p>\n<p>Friction is a force that opposes the relative motion of two surfaces in contact. In a system, friction can cause a delay in the response of the system to a change in input. This is because the friction force must be overcome before the system can move.<\/p>\n<p>A low friction coefficient means that there is less friction between the surfaces in contact. This means that the system will be able to respond more quickly to a change in input. As a result, the velocity lag error will be reduced.<\/p>\n<p>The other options are incorrect because they are not directly related to the friction coefficient. Option B, increased velocity lag error, is the opposite of what would be expected with a low friction coefficient. <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> Option C, increased speed of response, is not necessarily true, as the speed of response depends on other factors besides the friction coefficient.
