<h2 class="wp-block-heading" id="h-question-3-velocity-time-graph-for-uniform-velocity">Question 3: Velocity-Time Graph for Uniform Velocity</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>The velocity-time graph of an object moving with a uniform velocity is:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul class="wp-block-list"><!-- wp:list-item -->
<li>A) A straight line</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->

<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>C) A horizontal line</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>D) A diagonal line</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p><strong>Explanation:</strong><br>When an object moves with <strong>uniform velocity</strong>, the velocity remains constant over time. The graph is a <strong>horizontal line</strong> parallel to the time axis.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> C) Horizontal line</p>
