Unlike uniform circular motion (constant speed), non-uniform motion involves changes in both <strong>direction<\/strong> and <strong>magnitude<\/strong> of velocity, leading to a more complex relationship between velocity and acceleration.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Velocity in Curvilinear Motion<\/strong><\/h4>\n\n\n\n<p>Velocity is always <strong>tangent<\/strong> to the path of motion, indicating the direction the object is currently moving. Its <strong>magnitude<\/strong> represents the object\u2019s speed.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Acceleration in Curvilinear Motion<\/strong><\/h4>\n\n\n\n<p>Acceleration can be split into two components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tangential acceleration<\/strong>: This component is <strong>along the direction of velocity<\/strong> and changes the <strong>magnitude<\/strong> (speed) of the velocity.<\/li>\n\n\n\n<li><strong>Normal (or centripetal) acceleration<\/strong>: This component is <strong>perpendicular to the velocity vector<\/strong>, pointing toward the <strong>center of curvature<\/strong> of the path. It changes the <strong>direction<\/strong> of the velocity vector.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Combined Effect<\/strong><\/h4>\n\n\n\n<p>In <strong>non-uniform<\/strong> curvilinear motion, both the direction and magnitude of velocity change. Therefore, the <strong>acceleration vector is not purely tangent or perpendicular<\/strong> to the path. It is a <strong>vector sum<\/strong> of tangential and normal components.<\/p>\n\n\n\n<p>This means the <strong>acceleration vector can point in any direction depending on the curve and speed<\/strong>, and it is generally <strong>not parallel or perpendicular<\/strong> to the velocity vector at all times.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Why D is Correct<\/strong><\/h4>\n\n\n\n<p>Option D correctly captures this complexity:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cThe velocity and acceleration vectors can have both tangential and normal components.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p>This comprehensive description fits all cases of non-uniform curvilinear motion, making it the most accurate and complete option.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Incorrect Options:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A)<\/strong> Only true for straight-line acceleration with constant direction.<\/li>\n\n\n\n<li><strong>B)<\/strong> Applies only to tangential acceleration, ignoring the normal component.<\/li>\n\n\n\n<li><strong>C)<\/strong> True in uniform circular motion, but <strong>not<\/strong> in non-uniform motion.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following describes the relationship between velocity and acceleration in non-uniform curvilinear motion?
