In physics, it is defined as the change in velocity divided by the time taken for that change. It is a vector quantity, meaning it has both magnitude and direction. When an object speeds up, its acceleration is positive. When it slows down, its acceleration is negative (also called deceleration).<\/p>\n\n\n\n<p>To calculate the acceleration, the following formula is used:a=vf\u2212vita = \\frac{{v_f &#8211; v_i}}{t}a=tvf\u200b\u2212vi\u200b\u200b<\/p>\n\n\n\n<p>where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>aaa is the acceleration,<\/li>\n\n\n\n<li>vfv_fvf\u200b is the final velocity,<\/li>\n\n\n\n<li>viv_ivi\u200b is the initial velocity,<\/li>\n\n\n\n<li>ttt is the time interval.<\/li>\n<\/ul>\n\n\n\n<p>In this problem, the object starts with an initial velocity of 65 m\/s and increases its speed to 98 m\/s over a time period of 12 seconds. Substituting these values into the formula:a=98\u2009m\/s\u221265\u2009m\/s12\u2009s=33\u2009m\/s12\u2009s=2.75\u2009m\/s2a = \\frac{{98\\, \\text{m\/s} &#8211; 65\\, \\text{m\/s}}}{12\\, \\text{s}} = \\frac{33\\, \\text{m\/s}}{12\\, \\text{s}} = 2.75\\, \\text{m\/s}^2a=12s98m\/s\u221265m\/s\u200b=12s33m\/s\u200b=2.75m\/s2<\/p>\n\n\n\n<p>This result means that the object\u2019s velocity is increasing by 2.75 meters per second every second. In real-world terms, if this object were a car, its speed would be increasing smoothly by that rate throughout the 12-second period.<\/p>\n\n\n\n<p>Understanding acceleration is crucial in many areas of science and engineering, from analyzing motion in physics to designing safe transportation systems.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-241.jpeg\" alt=\"\" class=\"wp-image-233447\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>If the velocity of an object changes from 65 m\/s to 98 M\/s during a time interval of 12 s what is the acceleration of the object The Correct Answer and Explanation is: Answer: To find the acceleration, we use the formula:Acceleration=Final&nbsp;velocity\u2212Initial&nbsp;velocityTime\\text{Acceleration} = \\frac{{\\text{Final velocity} &#8211;
